Fork of D3 Course Code Along - Choropleth Map
This interactive choropleth map visualizes countries color-coded by income group on a natural Earth projection. A legend with animated transitions updates when the color scale changes. The visualization uses d3.geoPath with TopoJSON data from the World Atlas, and builds the map with SVG paths. Hover effects highlight individual countries, while zoom and pan are enabled through d3.zoom. World population data from CSV files supports additional context.
