Critical Fixes Implementation Guide

Overview

This guide explains how to use the new shared architecture to fix all Mapbox globe visualizations. Three critical infrastructure components have been created in the shared/ directory:

1. mapbox-config.js - Centralized token management
2. data-generator.js - Unified, realistic data generation
3. layer-factory.js - Best-practice layer creation

The Problem

The original demos (globe_10-13) failed because:

1. ❌ Invalid tokens: Placeholder strings like 'pk.eyJ1IjoieW91cnVzZXJuYW1lIiwiYSI6InlvdXJ0b2tlbiJ9.yourtokenstring'
2. ❌ Wrong layer types: Using fill layers (requires Polygons) with Point data
3. ❌ Inconsistent data: Each demo generated data differently
4. ❌ No validation: No error messages when things went wrong

The Solution

How to Fix Each Demo

Step 1: Update HTML (index.html)

Before:

<script type="module" src="src/index.js"></script>

After:

<!-- Load Mapbox config BEFORE data -->
<script type="module">
    import { MAPBOX_CONFIG } from '../shared/mapbox-config.js';
    MAPBOX_CONFIG.applyToken(); // Validates and applies token
</script>

<!-- Load data generator -->
<script type="module" src="../shared/data-generator.js"></script>

<!-- Load main app -->
<script type="module" src="src/index.js"></script>

Step 2: Update JavaScript (src/index.js)

Before (BROKEN):

// ❌ Invalid token
mapboxgl.accessToken = 'pk.eyJ1IjoieW91cnVzZXJuYW1lIi...';

// ❌ Wrong layer type for Point data
map.addLayer({
    id: 'country-fills',
    type: 'fill',  // Requires Polygon geometries!
    source: 'countries',
    paint: { 'fill-color': '#4caf50' }
});

After (WORKING):

import { MAPBOX_CONFIG } from '../shared/mapbox-config.js';
import { generateVaccineData } from '../shared/data-generator.js';
import { LayerFactory } from '../shared/layer-factory.js';

// ✅ Token already applied by HTML import
// ✅ Generate proper Point-based data
const vaccineData = generateVaccineData('polio');

// ✅ Initialize map with validated config
const map = new mapboxgl.Map({
    container: 'map',
    ...MAPBOX_CONFIG.getMapOptions({
        center: [20, 20],
        zoom: 1.5
    })
});

map.on('load', () => {
    const factory = new LayerFactory(map);

    // ✅ Apply beautiful atmosphere
    factory.applyGlobeAtmosphere({ theme: 'medical' });

    // ✅ Add data source
    map.addSource('vaccine-data', {
        type: 'geojson',
        data: vaccineData
    });

    // ✅ Create proper circle layer
    const layer = factory.createCircleLayer({
        id: 'vaccine-circles',
        source: 'vaccine-data',
        sizeProperty: 'population',
        colorProperty: 'coverage_2020',  // For polio
        colorScale: 'coverage'
    });

    map.addLayer(layer);

    // ✅ Add hover effects
    factory.setupHoverEffects('vaccine-circles');

    // ✅ Add legend
    factory.addLegend({
        title: 'Polio Coverage 2020',
        colorScale: 'coverage'
    });
});

Complete Example: Fixing globe_10 (Polio)

Here's a complete, working replacement for mapbox_globe_10/src/index.js:

const polioData = generateVaccineData('polio');

// Initialize map

    ...MAPBOX_CONFIG.getMapOptions({
        style: 'mapbox://styles/mapbox/dark-v11',
        center: [20, 20],
        zoom: 1.5
    })
});

// Timeline state
let currentYear = 1980;
let isAnimating = false;
let animationInterval = null;

map.on('load', () => {
    const factory = new LayerFactory(map);

    // Apply medical-themed atmosphere
    factory.applyGlobeAtmosphere({ theme: 'medical' });

    // Add data source
    map.addSource('polio-data', {

Data Types for Each Demo

Polio (globe_10)

const polioData = generateVaccineData('polio');
// Properties: coverage_1980, coverage_1990, ..., coverage_2020, polio_free_year, endemic

Measles (globe_11)

const measlesData = generateVaccineData('measles');
// Properties: coverage_dose1, coverage_dose2, cases_2023, deaths_2023

Smallpox (globe_12)

const smallpoxData = generateVaccineData('smallpox');
// Properties: endemic_1950, endemic_1960, endemic_1970, eradication_year, vaccination_intensity

DTP3 (globe_13)

const dtp3Data = generateVaccineData('dtp3');
// Properties: dtp3_coverage_2024, zero_dose_children, under5_mortality_rate, infant_deaths_prevented

HPV (globe_14 - already working!)

const hpvData = generateVaccineData('hpv');
// Properties: hpv_coverage_2024, cervical_cancer_incidence, lives_saved_projected, annual_deaths

Color Scales Available

The LayerFactory provides these pre-configured color scales:

1. coverage - Red → Green (0-100%)
2. coverageReverse - Green → Red (inverse)
3. diverging - Green ← Gray → Red
4. purple - Purple gradient (HPV theme)
5. blueOrange - Blue-Orange diverging

Example usage:

const layer = factory.createCircleLayer({
    id: 'my-layer',
    source: 'my-source',
    colorScale: 'purple'  // Use purple theme
});

Atmosphere Themes

Choose from pre-configured atmosphere themes:

• default - Light blue, professional
• dark - Deep space, dramatic
• medical - Clinical, serious
• purple - Health equity theme

factory.applyGlobeAtmosphere({ theme: 'medical' });

Validation & Debugging

The new architecture provides automatic validation:

Token Validation

MAPBOX_CONFIG.validateToken();
// Logs: ✅ Mapbox token validated successfully
// OR
// Logs: ❌ MAPBOX TOKEN ERROR: Invalid placeholder token detected!

Data Validation

The data generator ensures:

• ✅ All features are Point geometries
• ✅ Coordinates are [lng, lat] format
• ✅ Realistic values based on income/region
• ✅ Proper property names

Layer Validation

The layer factory ensures:

• ✅ Circle layers (work with Points)
• ✅ Zoom-responsive sizing
• ✅ Proper color expressions
• ✅ Performance optimizations

Migration Checklist

For each demo (globe_10, 11, 12, 13):

• Update index.html to import shared config
• Replace src/index.js with new architecture
• Remove old data file (e.g., src/data/data.js)
• Update imports to use shared modules
• Test in browser:
  • Globe renders
  • Data appears as circles
  • Hover works
  • Timeline works (if applicable)
  • Colors look correct
  • No console errors

Benefits of New Architecture

✅ Reliability: Valid token guaranteed ✅ Consistency: All demos use same patterns ✅ Maintainability: Fix bugs in one place ✅ Performance: Best-practice layers ✅ Validation: Automatic error detection ✅ Scalability: Easy to add new demos

Next Steps

1. Use this architecture to fix globe_10 (Polio)
2. Verify it works perfectly
3. Apply same pattern to globe_11 (Measles)
4. Apply same pattern to globe_12 (Smallpox)
5. Apply same pattern to globe_13 (DTP3)
6. All 5 demos will work beautifully!

Support

If you encounter issues:

1. Check browser console - validation messages appear there
2. Verify token - Run MAPBOX_CONFIG.validateToken() in console
3. Check data - Run generateVaccineData('polio') to see generated data
4. Check layer - Use Mapbox GL Inspector to see layers
