This choropleth map visualizes the states of India, with each state filled by a distinct categorical color and labeled with its name. The map uses the Mercator projection, positioned and scaled to center the country. The example employs `d3.geoPath` to generate SVG paths from the provided GeoJSON data, leveraging a categorical color scale for fills. State name labels are placed at each region's centroid, and the entire rendering is implemented using D3 v5 within a React-based context.
