This example displays a detailed choropleth map of Salem, India, using SVG paths rendered with a heavily zoomed-in Mercator projection. It loads TopoJSON data from a remote gist and converts it to GeoJSON features using the `feature` function from the `topojson` library. The React component fetches the data with a custom hook and renders each geographic feature as a styled path via `d3.geoPath`. The map emphasizes regional boundaries with a teal stroke, contrasting against a clean white background.
