This visualization displays a choropleth map of India, with each district and state boundary rendered as SVG paths. District polygons are filled with colors from `d3.scaleOrdinal` and `schemeCategory10`, while state outlines appear in green with hover effects turning districts black. The map uses `d3.geoMercator` projection and `d3.geoPath` to render TopoJSON data for districts and states. Users can pan and zoom via `d3.zoom`, with tooltips showing district and state names on hover.
