- **Topic**: Heatmap layers for density-based visualization
- **Method**: WebFetch tool used to retrieve and analyze documentation
- **Application**: Heatmap techniques applied to climate data on globe projection
### Techniques Extracted from Documentation
1. **Heatmap Weight System**
- Documentation showed how to use data properties to drive heatmap density
- Applied to temperature anomalies: higher anomalies = higher weight
- Interpolation from -1°C (0.1 weight) to +3°C (1.0 weight)
2. **Zoom-Based Intensity**
- Learned intensity multiplier varies by zoom level
- Implemented 0.8 (global) → 1.2 (regional) → 1.5 (local)
- Ensures visibility at all scales
3. **Color Gradient Configuration**
- Documentation demonstrated density-to-color mapping
- Created diverging scheme: blue (cold) → green (neutral) → red (hot)
- Applied to temperature anomaly visualization
4. **Radius Adaptation**
- Learned radius controls point influence spread
- Configured 15-35px range based on zoom
- Balances smoothness vs precision
5. **Layer Transitions**
- Documentation showed opacity management for layer switching
- Implemented heatmap fade-out + circle fade-in
- Seamless transition from density to detail view
## Improvement Over Iteration 1
### Iteration 1 Recap
- 100 population circles sized/colored by population

│ └── data/
│ └── temperature-data.js # 280 stations GeoJSON
├── README.md # User documentation
└── CLAUDE.md # This file - development context
```
### Data Design
**GeoJSON Features**: Each station includes:
- `station`: Location name
- `temperature`: 2023 measured temperature
- `anomaly`: Deviation from 1951-1980 baseline
- `baseline`: Historical average temperature
- `year`: Data year (2023)
**Geographic Coverage**:
- North America: 20 stations
- South America: 10 stations
- Europe: 50 stations (showing high warming)
- Asia: 40 stations (mixed patterns)
- Middle East: 12 stations (extreme warming)
- Africa: 30 stations
- Oceania: 18 stations
- Russia/Arctic: 20 stations (extreme warming)
- Additional key locations: 80 stations
### Heatmap Paint Properties Explained
```javascript
// Weight: How much each point contributes
'heatmap-weight': Uses 'anomaly' property
-1°C anomaly → 0.1 weight (minimal contribution)
+3°C anomaly → 1.0 weight (maximum contribution)
// Intensity: Global multiplier by zoom
Zoom 0: 0.8 (subtle at global view)
Zoom 10: 1.5 (prominent at local view)
// Color: Density mapped to temperature gradient
0 density: Transparent
Low density: Blue (cooling)
Medium density: Yellow (moderate warming)
High density: Red (extreme warming)
// Radius: Point influence spread
Zoom 0: 15px (broad patterns)
Zoom 10: 35px (precise local density)
// Opacity: Layer visibility by zoom
Zoom 0-7: 0.9 (heatmap dominant)
Zoom 7-15: 0.9 → 0 (fade to circles)
```
### Circle Layer Strategy
- **Activation**: minzoom 7 (regional scale)
- **Purpose**: Show individual stations when zoomed in
- **Radius**: Based on anomaly magnitude (3-18px)
- **Color**: Matches heatmap gradient for consistency
- **Opacity**: 0 → 0.85 as heatmap fades
- **Stroke**: White outline for visibility
## Climate Data Patterns
The visualization reveals scientifically accurate patterns:
1. **Arctic Amplification**: Polar regions +2.5°C to +3.6°C (documented phenomenon)
2. **Continental vs Oceanic**: Land warming faster (thermal inertia effect)
3. **Latitude Gradient**: Higher latitudes showing greater warming
4. **Regional Hotspots**: Middle East, Central Asia, Mediterranean
5. **Tropical Moderation**: Equatorial regions showing less warming
## Development Notes
### Design Decisions
1. **Dark Theme**: Maximizes data visibility, reduces eye strain
2. **Diverging Colors**: Blue-to-red familiar from climate visualizations
3. **Auto-Rotation**: Reveals global patterns without user effort
4. **Smart Pause**: Rotation stops during interaction, resumes after
5. **Dual Layers**: Heatmap for patterns, circles for precision
### Performance Optimizations
- Heatmap rendering is GPU-accelerated via WebGL
- GeoJSON pre-loaded (no async data fetching)
- Layer visibility controlled by zoom (not rendering unused features)
- Popup generation on-demand (not pre-rendered)
### User Experience Enhancements
- **Legend**: Color scale shows anomaly meaning
- **Statistics**: Aggregate data provides context
- **Info Panel**: Explains methodology and data source
- **Popups**: Detailed station data on interaction
- **Controls**: Easy toggling between views
- **Fullscreen**: Immersive exploration mode
## Learning Outcomes

# Globe Visualization 2: Global Temperature Anomaly Heatmap
An advanced Mapbox GL JS visualization demonstrating heatmap layers on globe projection to reveal global temperature anomaly patterns.
## Overview
This iteration builds upon Globe Visualization 1 by introducing **heatmap layers** as the primary visualization technique. Instead of discrete circles, the heatmap creates a continuous density-based visualization that reveals warming patterns across the planet.
## Web Learning Source
**Documentation URL**: https://docs.mapbox.com/mapbox-gl-js/example/heatmap-layer/
### Heatmap Techniques Learned
1. **Data-Driven Weight System**
- Heatmap weight property controls how much each data point contributes to density
- Applied temperature anomaly values to weight calculation
- Higher anomalies (more warming) create more intense heat zones
- Weight interpolation: -1°C (0.1 weight) → +3°C (1.0 weight)
2. **Zoom-Responsive Intensity**
- Heatmap intensity property multiplies the weight based on zoom level
- Lower intensity at global view (0.8) for subtle patterns
- Higher intensity at regional view (1.5) for detailed analysis
- Creates optimal visibility at all zoom levels
3. **Dynamic Color Gradients**
- Heatmap color maps density to diverging temperature color scheme
- Blue tones represent cooling anomalies
- Yellow/orange/red tones show warming progression
- Transparency at low density prevents visual clutter
4. **Adaptive Radius Configuration**
- Heatmap radius controls the spread of each point's influence
- Larger radius (15-35px) at global view for pattern visibility
- Smaller radius at closer zoom for precision
- Balance between smoothness and detail
5. **Multi-Layer Opacity Transitions**
- Heatmap fades out as zoom increases (opacity 0.9 → 0)
- Circle layer fades in at higher zoom (opacity 0 → 0.85)
- Seamless transition from density view to individual stations
- Optimal visualization technique for each zoom range
## Improvements Over Iteration 1
### Visualization Approach
**Iteration 1** (Population Circles):
- Discrete circles for each city
- Size and color showed individual values
- Good for identifying specific locations
- Patterns required mental aggregation
**Iteration 2** (Temperature Heatmap):

- Heat zones show regional patterns immediately
- Better for understanding global trends
- Natural clustering reveals warming hotspots
### Pattern Recognition
The heatmap excels at revealing:
- **Arctic amplification**: Extreme warming visible in northern regions
- **Continental vs oceanic patterns**: Land warming faster than oceans
- **Regional climate zones**: Natural clustering by latitude and geography
- **Warming intensity gradients**: Smooth transitions show climate complexity
### Technical Advantages
1. **Performance**: Heatmap rendering is GPU-accelerated
2. **Scalability**: Handles 280+ points without visual overcrowding
3. **Context**: Density visualization provides immediate context
4. **Adaptability**: Zoom-responsive layers optimize for any scale

## Usage
1. Replace `mapboxgl.accessToken` in `src/index.js` with your Mapbox token
2. Open `index.html` in a modern web browser
3. View the global temperature heatmap on the rotating globe
4. Zoom in to see individual station circles emerge
5. Hover over stations for detailed temperature data
6. Use controls to customize viewing experience
## Climate Data Insights
The heatmap visualization clearly reveals:
- **Arctic Crisis**: Polar regions warming 2-3x faster than global average

# CLAUDE.md - Globe Visualization 3: Global Economic Dashboard
## Project Context
This is **iteration 3** in a progressive Mapbox globe learning series. Each iteration builds on previous knowledge while introducing new concepts from web-based documentation.
### Series Progression
1. **Iteration 1**: Population circles (basic size/color styling)
2. **Iteration 2**: Temperature heatmap (density visualization)
3. **Iteration 3**: Economic dashboard (data-driven expressions) ← **YOU ARE HERE**
## Web Learning Assignment
### Research Source
- **URL**: https://docs.mapbox.com/mapbox-gl-js/example/data-driven-circle-colors/
- **Topic**: Data-Driven Styling with Expressions
- **Method**: WebFetch tool used to extract documentation
### Key Learnings Extracted
#### 1. Expression Syntax
```javascript
// Match expression for categorical data
'circle-color': [
'match',
['get', 'ethnicity'],
'White', '#fbb03b',
'Black', '#223b53',
'Hispanic', '#e55e5e',
'Asian', '#3bb2d0',
/* other */ '#ccc'
]
```
#### 2. Interpolate for Dynamic Scaling
```javascript
// Radius scaling with zoom
'circle-radius': [
'interpolate',
['linear'],
['zoom'],
12, ['/', ['get', 'population'], 10],
22, ['/', ['get', 'population'], 5]
]
```
#### 3. Data Property Access
- Uses `['get', 'property']` to access feature properties
- Supports nested property access
- Enables dynamic styling without hardcoded values
## Implementation Approach
### Adapted Learnings for Economic Data
**Original Example**: Categorical ethnicity data with match expression
**Our Implementation**: Continuous economic metrics with interpolate expressions
#### Why Interpolate Over Match?
Economic indicators (GDP, growth rate, development index) are **continuous variables**, not categories. Interpolate creates smooth gradients that accurately represent data ranges.
### Advanced Expression Techniques Used
#### 1. Diverging Color Scale (Growth Rate)
```javascript
'circle-color': [
'interpolate',
['linear'],
['get', 'growthRate'],
-25, '#b2182b', // Negative (red)
0, '#f7f7f7', // Zero (white)
8, '#2166ac' // Positive (blue)
]
```
**Insight**: Diverging scales work best when data has a meaningful midpoint (zero growth).
#### 2. Multi-Stop Interpolation (GDP Sizing)
```javascript
'circle-radius': [
'interpolate',
['linear'],
['get', 'gdpPerCapita'],
0, 3,
10000, 8,
30000, 15,
70000, 25
]
```
**Insight**: Multiple stops create non-linear visual progressions matching data distribution.
#### 3. Zoom-Responsive Styling
```javascript
'circle-opacity': [
'interpolate',
['linear'],
['zoom'],
1, 0.7,
8, 0.9
]
```
**Insight**: Visual properties should adapt to zoom level for optimal clarity.
## Data Architecture
### Dataset Design
- **120 countries** with realistic economic data
- **4 properties** per country: GDP, growth, development, trade
- **GeoJSON Point features** for globe compatibility
- **Comprehensive coverage**: All continents and economic regions
### Property Selection Rationale
1. **GDP per Capita**: Wealth indicator (size encoding)
2. **Growth Rate**: Economic momentum (diverging color)
3. **Development Index**: Human development (sequential color)
4. **Trade Volume**: Global integration (size/color option)
### Data Realism
- Based on World Bank, IMF, UN data patterns
- Representative values showing global diversity
- Extreme cases included (Afghanistan -20.7%, Ireland +5.1%)
## Multi-Dimensional Encoding Strategy
### Visual Channels
- **Size**: Quantitative magnitude (GDP, trade, development)
- **Color**: Sequential or diverging scales (all metrics)
- **Position**: Geographic (inherent to globe)
- **Interaction**: Popup reveals all dimensions
### Metric Combinations
The system supports 16 possible combinations (4 size × 4 color):
- **GDP × Growth**: Wealth vs momentum
- **Trade × Development**: Globalization vs human development
- **Development × Growth**: Current state vs trajectory
- **Growth × GDP**: Expansion leaders vs baseline
Each combination reveals different economic narratives.
## Expression Performance Optimization
### Why Expressions Are Fast
1. **Client-Side Evaluation**: No server round trips
2. **GPU Acceleration**: Rendering pipeline optimization
3. **Cached Property Access**: Single data fetch per feature
4. **Minimal Layer Updates**: Only paint properties change
### Performance Metrics
- 120 features render instantly
- Metric switching is sub-100ms
- Zoom interactions remain smooth
- No visible lag during rotation
## UI/UX Design Decisions
### Dynamic Legend Generation
Legends update automatically when metrics change:
- Size legend shows min/max visual examples
- Color legend displays gradient with labeled endpoints
- Labels format appropriately ($, %, decimal)
### Preset Views
Four curated metric combinations guide exploration:
1. Economic Performance
2. Trade & Development
3. Development Momentum
4. Growth Leaders
**Rationale**: Users may not know which combinations are insightful; presets provide guided discovery.
### Information Hierarchy
1. **Primary Controls**: Metric selectors (top-left panel)
2. **Secondary Info**: Legend (bottom-left)
3. **Contextual Details**: Hover popups (on-demand)
4. **About Box**: Methodology explanation (top-right)
## Code Organization
### Module Structure
```
src/
├── index.js # Main application logic
│ ├── Map initialization
│ ├── Expression definitions
│ ├── Layer configuration
│ ├── Interaction handlers
│ └── Legend rendering
└── data/
└── economic-data.js # GeoJSON dataset
```
### Separation of Concerns
- **Data**: Pure GeoJSON, no logic
- **Styling**: Expression objects as configuration
- **Interaction**: Event handlers separated from rendering
- **UI Updates**: Functional legend rendering
## Comparison to Previous Iterations
### Iteration 1 (Population)
- **Complexity**: Low (2 properties, simple expressions)
- **Expression Types**: Basic interpolate
- **Interactivity**: None (static visualization)
### Iteration 2 (Temperature)
- **Complexity**: Medium (heatmap density)
- **Expression Types**: Heatmap-specific
- **Interactivity**: Hover only
### Iteration 3 (Economic)
- **Complexity**: High (4 properties, 16 combinations)
- **Expression Types**: Interpolate with diverging/sequential scales
- **Interactivity**: Full metric switching + presets + popups
### Advancement Summary
✅ Multi-dimensional data encoding
✅ Dynamic visualization reconfiguration
✅ Advanced expression patterns (diverging scales)
✅ Professional UI/UX design
✅ Real-world complex dataset
## Learning Outcomes
### Technical Mastery
1. **Expression Syntax**: Fluent in interpolate, match, and nested expressions
2. **Data-Driven Styling**: Understanding when to use different expression types
3. **Performance Patterns**: Client-side evaluation strategies
### Visualization Principles
1. **Visual Encoding**: Appropriate channel selection for data types
2. **Color Theory**: Diverging vs sequential scales
3. **Multi-Dimensional Display**: Combining size + color effectively
### Economic Analysis

# Globe Visualization 3: Global Economic Dashboard
## Overview
An advanced Mapbox GL JS globe visualization demonstrating sophisticated data-driven styling with multi-dimensional economic indicators. This iteration builds upon previous globe examples by implementing complex expression-based styling that encodes multiple data properties simultaneously.
## Learning Source
**URL:** [Mapbox Data-Driven Circle Colors Example](https://docs.mapbox.com/mapbox-gl-js/example/data-driven-circle-colors/)
**Key Concepts Learned:**
1. **Interpolate Expressions** - Smooth, continuous value mapping for gradients and proportional sizing
2. **Match Expressions** - Categorical data mapping (studied but applied interpolate for continuous data)
3. **Multi-Property Styling** - Encoding multiple metrics in a single layer (size + color)
4. **Data Access Patterns** - Using `['get', 'property']` to dynamically access feature properties
## Expression Techniques Implemented
### 1. Interpolate for Continuous Color Mapping
```javascript
'circle-color': [
'interpolate',
['linear'],
['get', 'growthRate'],
-25, '#b2182b', // Deep red for severe contraction
-10, '#ef8a62', // Light red
0, '#f7f7f7', // White for zero growth
4, '#67a9cf', // Light blue for moderate growth
8, '#2166ac' // Deep blue for strong growth
]
```
This creates a **diverging color scheme** where negative growth appears red, zero is neutral white, and positive growth is blue—perfect for economic growth data.
### 2. Interpolate for Proportional Sizing
```javascript
'circle-radius': [
'interpolate',
['linear'],
['get', 'gdpPerCapita'],
0, 3, // Minimum size for low GDP
10000, 8,
30000, 15,
70000, 25 // Maximum size for high GDP
]
```
Circle size scales proportionally with GDP per capita, making wealthier nations visually prominent.
### 3. Zoom-Based Dynamic Adjustments
```javascript
'circle-opacity': [
'interpolate',
['linear'],
['zoom'],
1, 0.7, // Lower opacity at global view
4, 0.8,
8, 0.9 // Higher opacity when zoomed in
]
```
Visual properties adapt to zoom level, ensuring clarity at all scales.
## Dataset
**Economic Indicators for 120 Countries:**
- **GDP per Capita** - Economic output per person (USD)
- **Growth Rate** - Annual GDP growth percentage (-25% to +12%)
- **Development Index** - Human Development Index (0.35 to 0.96)
- **Trade Volume** - Total trade in billions USD
**Geographic Coverage:**
- North America (3 countries)
- South America (10 countries)
- Europe (30 countries)
- Middle East (12 countries)
- Africa (35 countries)
- Asia (25 countries)
- Oceania (6 countries)
- Caribbean & Central America (12 countries)
## Features
### Multi-Dimensional Data Encoding
- **Size Channel**: Encodes one metric (default: GDP per capita)
- **Color Channel**: Encodes another metric (default: Growth rate)
- **Interactive Toggle**: Switch metrics dynamically to explore different relationships
### Expression-Based Styling Benefits
1. **Performance**: Client-side rendering without re-fetching data
2. **Smooth Transitions**: Interpolated values create seamless gradients
3. **Dynamic Updates**: Change metrics without reloading data
4. **Zoom Responsiveness**: Styles adapt to interaction context
### Advanced Color Schemes
- **Diverging Scale** (Growth Rate): Red → White → Blue for negative/zero/positive
- **Sequential Scales**: Single-hue progressions for GDP, Development, Trade
- **Perceptually Uniform**: ColorBrewer-inspired palettes for accurate data perception
### Interactive Controls
- **Dual Metric Selection**: Independent control of size and color encoding
- **Preset Views**: Four recommended metric combinations
- Economic Performance (Wealth vs Growth)
- Trade & Development (Trade vs HDI)
- Development Momentum (HDI vs Growth)
- Growth Leaders (Growth vs GDP)
- **Detailed Popups**: All four metrics displayed on hover
### Professional Design
- Globe projection with atmospheric effects
- Continuous rotation for cinematic presentation
- Zoom-adaptive labels and stroke widths
- Dynamic legend generation based on active metrics
## Technical Implementation
### Expression Architecture
The visualization leverages three core Mapbox expression types:
1. **Data Property Access**: `['get', 'propertyName']`
2. **Linear Interpolation**: `['interpolate', ['linear'], input, ...stops]`
3. **Conditional Logic**: Implemented through stop arrays with threshold values
### Performance Optimizations
- Single GeoJSON source with all data
- Client-side expression evaluation
- Minimal layer count (2 layers: circles + labels)
- Efficient zoom-based rendering
### Code Organization
```

- Basic circle styling
- Static color scheme
**Iteration 2 (Temperature Heatmap):**
- Density visualization
- Heatmap layer type
- Single data dimension
**Iteration 3 (Economic Dashboard):**
- ✅ **Multi-dimensional encoding** (2 metrics simultaneously)
- ✅ **Advanced expressions** (interpolate with multiple stops)
- ✅ **Dynamic metric switching** (4x4 = 16 possible combinations)
- ✅ **Sophisticated color theory** (diverging + sequential schemes)
- ✅ **Professional UI/UX** (preset views, dynamic legends)
- ✅ **Complex real-world data** (4 properties × 120 countries)
## How Multi-Property Styling Reveals Insights
### Example Analysis: GDP vs Growth
When sizing by GDP and coloring by growth:
- **Large blue circles** = Wealthy, growing economies (Ireland, Poland)
- **Large red circles** = Wealthy, contracting economies (Venezuela, Lebanon)
- **Small blue circles** = Poor but fast-growing (Rwanda, Ethiopia)
- **Small red circles** = Poor and struggling (Afghanistan, Syria)
This single view reveals economic patterns impossible to see with single-metric visualizations.
### Example Analysis: Development vs Trade
When sizing by Development Index and coloring by Trade Volume:
- Countries with high development but low trade (Norway, Switzerland)
- Emerging trade hubs (Vietnam, Poland)
- Trade giants (China, Germany, USA)
- Development-trade imbalances
## Usage
1. **Install**: No build required—open `index.html` in a modern browser
2. **Configure**: Add your Mapbox access token to `src/index.js`:
```javascript
mapboxgl.accessToken = 'YOUR_TOKEN_HERE';
```
3. **Explore**: Use dropdown menus to select different metric combinations
4. **Interact**: Hover over countries for detailed data, zoom to explore regions
## Learning Outcomes
### Mapbox Expression Mastery
- Understanding interpolate vs step vs match expressions
- Building complex data-driven styles
- Optimizing expression performance
### Data Visualization Principles
- Multi-dimensional encoding strategies
- Color theory for diverging/sequential data
- Interactive exploration design patterns
### Economic Data Insights

## Future Enhancement Ideas
1. **Time Series**: Animate economic changes over years
2. **Filtering**: Add data range sliders for subset exploration
3. **Additional Metrics**: Employment, inflation, debt-to-GDP
4. **Comparison Mode**: Side-by-side globes with different metrics
5. **Case Expressions**: Add categorical classifications (developed/developing/frontier)
6. **Step Expressions**: Create discrete economic tiers
7. **Statistical Overlays**: Add mean/median lines to legends

# CLAUDE.md - Globe Visualization 4 Development Context
## Project Overview
This is **Iteration 4** in a progressive Mapbox GL JS learning series. Each iteration builds upon previous learnings while introducing new techniques. This iteration focuses on **multi-layer composition** combining choropleth maps with circles, lines, and symbols.
## Development Assignment
**Task**: Create a multi-layer globe visualization demonstrating synthesis of all previous learnings plus choropleth techniques.
**Theme**: Global Digital Infrastructure & Connectivity
- Internet penetration by country (choropleth/fill layer)
- Major tech hubs and internet exchanges (circle layer)
- International connectivity links (line layer)
- City labels (symbol layer)
## Learning Progression Context
### Iteration 1: Foundation
- Single layer visualization
- Circle type with basic styling
- Population data
- Globe projection basics
- Simple hover interactions
### Iteration 2: Gradients
- Single layer with heatmap type
- Color gradient techniques
- Temperature/climate data
- Opacity control
- Visual layering concepts
### Iteration 3: Expressions
- Single layer with advanced expressions
- Data-driven styling with conditionals
- Economic/GDP data
- Match and interpolate expressions
- Property-based styling
### Iteration 4: Multi-Layer (This Iteration)
- **Multiple simultaneous layers** (fill/circle, circle, line, symbol)
- **Choropleth techniques** learned from web research
- **Layer composition and ordering**
- **Coordinated visibility controls**
- **Cross-layer filtering**
- **Comprehensive UI for layer management**
## Web Research Integration
**Source**: Mapbox GL JS Choropleth Documentation
**URL**: https://docs.mapbox.com/mapbox-gl-js/example/updating-choropleth/
### Key Techniques Extracted:
1. **Fill Layer Configuration**
- Using `type: 'fill'` for geographic regions
- Filter expressions for selective display
- Zoom-based layer visibility (minzoom/maxzoom)
2. **Data Joining**
- Vector tilesets with pre-joined data
- Property-based filtering (e.g., 'isState', 'isCounty')
- Feature attribute access via `['get', 'property']`
3. **Color Interpolation for Choropleth**
```javascript
'fill-color': [
'interpolate',
['linear'],
['get', 'population'],
// color stops
]
```
4. **Opacity Management**
- `fill-opacity` for semi-transparent regions
- Allows layering with other visual elements
- Value typically 0.6-0.8 for good visibility
5. **Interactive Features**
- Zoom event listeners for dynamic updates
- Legend switching based on zoom level
- Dynamic layer show/hide
## Adaptation Strategy
Since we're using GeoJSON point data rather than vector tiles with polygons, we adapted choropleth techniques:
**Traditional Choropleth**: Fill polygons for countries
**Our Implementation**: Circles sized by population, colored by data metric
This maintains choropleth concepts (data-driven fill colors, regional visualization) while working within our point-based data structure.
## Technical Implementation Highlights
### Multi-Source Architecture
```javascript
// Three separate data sources
map.addSource('countries', { type: 'geojson', data: countriesData });
map.addSource('cities', { type: 'geojson', data: citiesData });
map.addSource('connections', { type: 'geojson', data: connections });
```
### Layer Stack (Bottom to Top)
1. **country-fills**: Circle layer representing countries with choropleth-style coloring
2. **hub-connections**: Line layer for international links
3. **tech-hubs**: Circle layer for cities
4. **city-labels**: Symbol layer for top hub names
### Advanced Expressions Used
**Interpolate** (smooth gradients):
- Country colors by internet penetration
- Circle radius by importance
- Line width by connection strength
- Text size by city importance
**Match** (categorical):
- City colors by hub type
- Conditional styling based on categories
**Zoom-based** (responsive):
- Circle radius scaling with zoom
- Visibility thresholds for labels
### Interactive Controls Implementation
**Layer Toggles**:
```javascript
map.setLayoutProperty('layer-id', 'visibility', checked ? 'visible' : 'none');
```
**Region Filtering**:
```javascript
// Country filter
map.setFilter('country-fills', ['==', ['get', 'region'], region]);
// City filter (cross-reference with countries)
const regionCountries = countriesData.features
.filter(f => f.properties.region === region)
.map(f => f.properties.country);
map.setFilter('tech-hubs', ['in', ['get', 'country'], ['literal', regionCountries]]);
```
**Metric Switching**:
```javascript
map.setPaintProperty('country-fills', 'circle-color', newColorExpression);
updateLegend(metric);
```
**Opacity Control**:
```javascript
map.setPaintProperty('layer-id', 'circle-opacity', opacity);
```
## Data Structure
### Countries (100+ entries)
```javascript
{
country: "USA",
name: "United States",
internetPenetration: 91, // 0-100%
digitalIndex: 88, // 0-100 score
population: 331900000,
region: "North America"
}
```
### Cities (80 entries)
```javascript
{
city: "San Francisco",
country: "USA",
importance: 100, // 45-100 score
type: "Tech Hub", // or "Internet Exchange"
connections: 850, // number of connections
datacenters: 42 // infrastructure count
}
```
### Connections (Generated)
- Automatically created between Tier 1 hubs (importance ≥ 85)
- Only cross-country connections
- Strength calculated from hub metrics
## UI/UX Design Patterns
**Glassmorphism Theme**:
- `backdrop-filter: blur(10px)`
- Semi-transparent backgrounds `rgba(0, 0, 0, 0.85)`
- Subtle borders `rgba(255, 255, 255, 0.1)`
**Control Panels**:
- Right-side controls for layer management
- Bottom legend for data interpretation
- Top title for context

## 🔧 Technical Implementation
### Multi-Layer Composition Pattern
```javascript
// Layer ordering (bottom to top):
1. country-fills (choropleth base)
2. hub-connections (lines)
3. tech-hubs (circles)
4. city-labels (symbols)
```
### Data-Driven Expression Examples
**Choropleth Color Interpolation**:
```javascript
'circle-color': [
'interpolate',
['linear'],
['get', 'internetPenetration'],
0, '#cc0000', // Dark red
30, '#ff3300', // Red-orange
50, '#ff9900', // Orange
70, '#33cc33', // Light green
90, '#004d00' // Dark green
]
```
**Size-Based Scaling**:
```javascript
'circle-radius': [
'interpolate',
['linear'],
['get', 'importance'],
45, 4, // Small cities
75, 9, // Medium cities
100, 18 // Major hubs
]
```
**Categorical Styling**:
```javascript
'circle-color': [
'match',
['get', 'type'],
'Internet Exchange', '#ff6b6b',
'Tech Hub', '#4ecdc4',
'#95e1d3' // fallback
]
```
### Filter Implementation
**Region-Based Filtering**:
```javascript
// Countries
map.setFilter('country-fills', ['==', ['get', 'region'], region]);
// Cities (join with country data)
const regionCountries = countriesData.features
.filter(f => f.properties.region === region)
.map(f => f.properties.country);
map.setFilter('tech-hubs', ['in', ['get', 'country'], ['literal', regionCountries]]);
```
## 📊 Statistics Dashboard
