This visualization renders a choropleth map of Indian states using a geoMercator projection. It loads TopoJSON data from a remote GitHub repository and converts it to GeoJSON with the topojson `feature` method, then draws each state as an SVG path using `d3.geoPath`. A categorical `scaleOrdinal` with `schemeCategory10` assigns colors to states. State names appear as SVG text elements positioned at path centroids via `pathGenerator.centroid`. The code uses D3 v5 selection methods like `selectAll` and `enter`/`append`, with a React-based bundle.
