DATASET STATISTICS:
- Total features: 127
- Country polygons: 80
- Outbreak points: 47
- Total file size: ~100 KB
- Lines of code: 1,967

VISUALIZATION FEATURES:
✓ Globe projection with atmospheric fog
✓ Dual-layer choropleth + proportional symbols
✓ Interactive popups (countries + outbreaks)
✓ Layer toggle controls
✓ Auto-rotation animation
✓ Pulse effects on outbreak points
✓ Real-time statistics panel
✓ Responsive legend

KEY DATA INSIGHTS:
- 83% global first dose coverage (below 95% threshold)
- 74% global second dose coverage (critical gap)
- 4.1M cases, 48.1K deaths in 2023
- 20% increase in cases (2022→2023)
- Outbreaks expanded from 36 to 57 countries
- Clear correlation: low coverage → more outbreaks

COVERAGE DISTRIBUTION:
- Low-income countries: 64% average coverage
- Middle-income countries: 86% average coverage
- High-income countries: 95%+ average coverage

OUTBREAK HOTSPOTS:
- DR Congo: 143,670 cases (72% coverage)
- Nigeria: 87,350 cases (68% coverage)
- Yemen: 78,940 cases (58% coverage)
- Syria: 56,780 cases (52% coverage)
- India: 234,560 cases (87% coverage - large population)

GEOGRAPHIC COVERAGE:
Africa: 22 countries
Asia: 18 countries
Europe: 20 countries
Americas: 12 countries
Middle East: 12 countries
Oceania: 3 countries

MAPBOX TECHNIQUES USED:
✓ Globe projection with setFog()
✓ Data-driven expressions
✓ Multi-source layer management
✓ Interpolated color scales
✓ Event-based interactivity
✓ RequestAnimationFrame animations
✓ Layer visibility toggles

RESEARCH CONTEXT:
Based on WHO/UNICEF findings:
- 60M lives saved through vaccination (2000-2023)
- 90% reduction in incidence/mortality/DALYs (1990-2021)
- Recent backsliding threatens decades of progress
- Conflict zones show lowest coverage

SETUP REQUIRED:
1. Get Mapbox access token from mapbox.com
2. Replace token in src/index.js line 4
3. Run local server (python -m http.server 8000)
4. Open http://localhost:8000

PUBLIC HEALTH MESSAGE:
The visualization clearly demonstrates that vaccination saves lives.
Every percentage point increase in coverage prevents thousands of
cases and hundreds of deaths. The 95% herd immunity threshold is
achievable with sustained investment in routine immunization programs.
