This visualization displays the districts of India as colored polygons, with state boundaries outlined in black. District polygons are colored according to their state, using a categorical color scheme, and each includes a hover tooltip showing the district and state name. The map supports zooming and panning via d3.zoom. The code uses d3.json to load TopoJSON data, d3.geoMercator with clipExtent, and d3.geoPath to render the features.
