This example shows a choropleth-style map of India rendered in SVG, with each state filled in light green. The map uses a D3 geoMercator projection centered on the country’s coordinates, with d3.geoPath generating the state boundaries from TopoJSON data fetched from a remote gist. React components manage the data-loading hook (useData) and the Map component, while the map is displayed at full window size on a grey background.
