This interactive map of India colors each state by cultural region—North, South, East, West, Northeast, and Central—using a D3 ordinal color scale over a Mercator projection via d3.geoPath. The SVG renders state boundaries from an external GeoJSON file, and hovering triggers a tooltip showing 2021 population estimates from embedded data. The example uses d3.v7 and topojson-client to load and display geographic features.
