This example displays a choropleth map of India, rendering each state as a distinct colored path using geographic features loaded from a GitHub gist. The visualization employs a Mercator projection via `d3.geoMercator` and converts TopoJSON data to GeoJSON features with the `topojson.feature` function. Each state is drawn as an SVG path generated by `d3.geoPath`, with fill colors assigned from `d3.scaleOrdinal` and `schemeCategory10`. The map includes a title and uses hover styling, with all rendering handled through React and D3 v5.
