This example displays a choropleth map of India, using color to differentiate each state. The visualization is rendered as SVG paths generated with `d3.geoPath` and a `geoMercator` projection, with state names placed at each region’s centroid. It loads TopoJSON data from a GitHub gist, processes it with the `topojson.feature` API, and colors states using `d3.scaleOrdinal` and `d3.schemeCategory10`. The map also includes hover styling through CSS, turning states white when moused over.
