Visualization Features

Interactive World Map

• Color-coded regions: Countries are colored by WHO region, with color intensity indicating total program count
• Hover details: Mouse over any country to see:
  • Region name
  • Total programs in that region
  • Breakdown by training content type (Cognition, Communication, Hearing, Mobility, Self-care, Vision)
• Geographic context: Easily identify regional patterns and gaps in assistive technology education
• Gray countries: Indicate no data available for that country

Stacked Bar Chart

• Regional comparison: Shows all WHO regions with programs
• Content type breakdown: Each bar is stacked by training content type
• Color-coded types: Different colors represent different training focuses
• Interactive bars: Hover over any segment to see the region and specific content type count

Legends

1. Training Content Types Legend: Shows all content types with their assigned colors
2. Region Totals Legend: Shows each region with color intensity and total program count

Technologies Used

• D3.js v7.6.1 — Data visualization
• TopoJSON — Geographic data format
• World Atlas — Country boundary data

Data Processing

• Programs are aggregated by WHO region and training content type
• Content type names are normalized from truncated CSV values
• Countries are colored by their parent WHO region
• Total program count per region determines color intensity
• Stacked bars show content type composition for each region
• Data period: 2021

Notes

• If you update the CSV file, ensure the Location column contains country names that match TopoJSON data
• The visualization uses Natural Earth country boundaries at 110m resolution
• For best viewing experience, use a modern web browser with JavaScript enabled
• Content type training categories are automatically detected and normalized from the Dim1 column
