# SDG Network Visualization - Analysis & Strategy
|
||||
|
||||
## Executive Summary
|
||||
|
||||
I've analyzed the existing SDG network modelling project and designed a **web-enhanced infinite loop system** that will progressively generate sophisticated force-directed network visualizations with automatic API discovery.
|
||||
|
||||
### What Was Reviewed
|
||||
|
||||
**Existing SDG Network Project** (`ai_docs/sdg-network-modelling/`):
|
||||
- Python notebooks fetching UN SDG API data
|
||||
- D3.js v3 force-directed graph visualization
|
||||
- Basic network showing: Geographic areas ↔ Ecosystem Capitals ↔ SDGs ↔ Targets
|
||||
- Simple interactions: hover tooltips, drag nodes
|
||||
- Single API source (UN Statistics)
|
||||
|
||||
**Current Limitations:**
|
||||
- Outdated D3.js version (v3 vs current v7)
|
||||
- Single hardcoded API
|
||||
- Basic visual design (simple circles/lines)
|
||||
- Limited interactivity (just hover)
|
||||
- No progressive enhancement
|
||||
- No web learning integration
|
||||
|
||||
## New System Design
|
||||
|
||||

|
||||
properties: {
|
||||
value: number,
|
||||
unit: "string",
|
||||
timestamp: "date",
|
||||
source_api: "api_name",
|
||||
// ... domain-specific attributes
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Edge Structure

|
||||
- ✅ **New**: Automatic API discovery, multiple sources combined
|
||||
|
||||
### **Visualization:**
|
||||
- ❌ **Old**: Basic circles and lines, single color scheme
|
||||
- ✅ **New**: Rich node/edge properties, dynamic sizing, multi-attribute encoding
|
||||
|
||||
### **Interactivity:**
|
||||
- ❌ **Old**: Simple hover tooltip
|
||||
- ✅ **New**: Search, filter, zoom, click actions, side panels, exports
|
||||
|
||||
### **Learning:**
|
||||
- ❌ **Old**: Static implementation
|
||||
- ✅ **New**: Each iteration learns from web and improves
|
||||
|
||||

|
||||
- ❌ **Old**: D3.js v3 (outdated)
|
||||
- ✅ **New**: D3.js v7 (modern), latest techniques
|
||||
|
||||
## Quality Metrics
|
||||
|
||||
Each iteration is evaluated on:
|
||||
|
||||
### **Data Richness:**
|
||||
- Number of API sources (1 → 5+)
|
||||
- Total nodes/edges
|
||||
- Data update frequency
|
||||
|
||||
### **Visual Quality:**
|
||||
- Color coding sophistication
|
||||
- Label readability
|
||||
- Animation smoothness (60fps)
|
||||
- Layout clarity
|
||||
|
||||
### **Interactivity:**
|
||||
- Number of features (hover → search → filter → AI)
|
||||
- Response time
|
||||
- Information density
|
||||
|
||||
### **Technical Innovation:**
|
||||
- New techniques applied
|
||||
- Performance improvements
|
||||
- Code quality
|
||||
|
||||
## Advanced Use Cases
|
||||
|
||||
### **Compare Algorithms:**
|
||||
Generate iterations with different force algorithms:
|
||||
```bash
|
||||
# Each iteration learns a different layout algorithm
|
||||
> /project:infinite-web specs/sdg_network_progressive.md algorithm_comparison 8
|
||||
```
|
||||
|
||||
### **Domain-Specific Networks:**
|
||||
Focus on specific data domains by modifying the spec:
|
||||
```bash
|
||||
# Ocean/marine data network
|
||||
> /project:infinite-web specs/ocean_network_progressive.md ocean_viz 10
|
||||
|
||||
# Climate change network
|
||||
> /project:infinite-web specs/climate_network_progressive.md climate_viz 15
|
||||
```
|
||||
|
||||
### **Real-Time Dashboards:**
|
||||
Advanced iterations include streaming data:
|
||||
```bash
|
||||
# Generate real-time monitoring dashboards
|
||||
> /project:infinite-web specs/sdg_network_progressive.md realtime_sdg 20
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### **API Access Issues:**
|
||||
- Some APIs require keys → iterations handle gracefully with fallbacks
|
||||
- CORS errors → iterations use proxy or alternatives
|
||||
- Rate limits → iterations implement caching
|
||||
|
||||
### **Performance:**
|
||||
- Large graphs → iterations use Canvas or WebGL
|
||||
- Slow rendering → iterations implement LOD and culling
|
||||
- Memory issues → iterations use virtualization
|
||||
|
||||
### **Browser Compatibility:**
|
||||
- All iterations target modern browsers (Chrome, Firefox, Safari, Edge)
|
||||
- Fallbacks for older browsers where reasonable
|
||||
- Progressive enhancement ensures basic functionality
|
||||
|
||||
## Next Steps

<h3>Data Source & Learning Documentation</h3>
|
||||
<p><strong>API Source:</strong> World Bank Open Data API (https://api.worldbank.org/v2/)</p>
|
||||
<p><strong>Indicators:</strong> CO2 Emissions (EN.ATM.CO2E.PC), Forest Area (AG.LND.FRST.ZS), Renewable Energy (EG.FEC.RNEW.ZS), Access to Electricity (EG.ELC.ACCS.ZS), PM2.5 Air Pollution (EN.ATM.PM25.MC.M3)</p>
|
||||
<p><strong>Web Learning Source:</strong> https://d3-graph-gallery.com/network.html</p>
|
||||
<p><strong>Techniques Applied:</strong></p>
|
||||
<ul style="margin: 5px 0; padding-left: 20px;">
|
||||
<li><strong>Color Scales:</strong> d3.scaleOrdinal() with d3.schemeCategory10 for categorical indicator types</li>
|
||||
<li><strong>Node Sizing:</strong> d3.scaleLinear() for proportional sizing based on data magnitude (5-25px range)</li>
|
||||
<li><strong>Force Simulation:</strong> Multi-body forces, link forces, collision detection, and centering</li>
|
||||
<li><strong>Visual Encodings:</strong> Size encodes value, color encodes category, edge width encodes correlation strength</li>
|
||||
<li><strong>Edge Styling:</strong> Curved paths with variable stroke-width based on relationship strength</li>
|
||||
<li><strong>Interactivity:</strong> Drag simulation, hover tooltips with rich data, zoom/pan behavior</li>
|
||||
</ul>
|
||||
<p><strong>Network Structure:</strong> Countries as nodes, environmental indicator correlations as edges. Nodes sized by normalized indicator values, colored by indicator category, connected when indicators show regional correlations.</p>

<h3>Advanced Color Encoding Strategy</h3>
|
||||
|
||||
<p><strong>Multi-Attribute Encoding:</strong></p>
|
||||
<ul style="margin: 8px 0; padding-left: 20px;">
|
||||
<li><strong>Node Fill Color:</strong> SDG category (categorical - d3.schemeCategory10 default)</li>
|
||||
<li><strong>Node Border Color:</strong> Impact magnitude (sequential - d3.interpolateViridis default)</li>
|
||||
<li><strong>Node Opacity:</strong> Data quality/confidence (0.4-1.0 range)</li>
|
||||
<li><strong>Node Size:</strong> Impact magnitude (radius 8-28px)</li>
|
||||
<li><strong>Edge Color:</strong> Dynamic gradients from source to target node colors</li>
|
||||
<li><strong>Edge Opacity:</strong> Connection strength (0.2-0.8 range)</li>
|
||||
</ul>
|
||||
|
||||
<p><strong>Web Learning Source:</strong> Observable HQ - D3 Color Legend (@d3/color-legend)</p>
|
||||
<p><strong>Techniques Applied:</strong></p>
|
||||
<ul style="margin: 8px 0; padding-left: 20px;">
|
||||
<li>Perceptually uniform color scales (Viridis, Plasma, Cividis) for sequential encoding</li>
|
||||
<li>Categorical color schemes (Category10, Accent, Dark2) for SDG categories</li>
|
||||
<li>Custom interactive legends with click-to-filter functionality</li>
|
||||
<li>Gradient bars for continuous scale visualization</li>
|
||||
<li>Multi-dimensional encoding: fill + border + opacity + size</li>
|
||||
<li>Dynamic color scheme switching for real-time exploration</li>
|
||||
</ul>
|
||||
|
||||

<strong>Iteration 7: Exploratory Analysis with Brushing & Linking</strong><br>
|
||||
This visualization demonstrates advanced exploratory data analysis using coordinated multiple views.
|
||||
Rectangle brush on the network to select nodes, and observe synchronized highlighting across all views.
|
||||
Features d3.brush() for selection, coordinated view updates, and multi-select capability (Shift+Click).<br>
|
||||
<strong>Web Learning:</strong> Techniques from <a href="https://observablehq.com/@d3/brushable-scatterplot" target="_blank">D3 Brushable Scatterplot</a> -
|
||||
Applied brush event handling, selection propagation via dispatch, coordinated filtering across views, and synchronized visual feedback.<br>

<strong>Iteration 8 - Advanced D3: Hierarchical Networks & Transitions</strong><br>
|
||||
<strong>Web Source:</strong> <a href="https://observablehq.com/@d3/force-directed-tree" target="_blank">D3 Force-Directed Tree</a><br>
|
||||
<strong>Techniques Applied:</strong> d3.hierarchy() for hierarchical data processing, force simulation with link/charge/center forces, collapsible nodes (click to expand/collapse), multiple layout algorithms (force/tree/radial/cluster), smooth d3.transition() animations (500ms, easeQuadInOut), state management with URL parameters, zoom-to-fit functionality, hierarchical parent-child link constraints<br>
|
||||
<strong>Hierarchy:</strong> SDG Goals → Targets → Indicators (3-level taxonomy), embedded data for instant load
