This interactive visualization displays the states and districts of India on a zoomable SVG map. The code uses `d3.geoMercator` for projection and `d3.geoPath` to render geographic features, with district polygons filled via `scaleOrdinal` and `schemeCategory10`. It loads GeoJSON data from topojson files and applies a zoom behavior to pan and scale the map. Hovering over a district changes its fill color, while tooltips show the district and state names.
