This visualization displays a choropleth map of India, rendering both state boundaries and district-level subdivisions. Districts are filled with categorical colors using a `d3.scaleOrdinal` with `schemeCategory10`, and hovering over a district turns it black. The map uses a `d3.geoMercator` projection and `d3.geoPath` to draw the geometry. It is built with React and D3, pulling TopoJSON data from GitHub sources for state and district boundaries. Pan and zoom interactions are enabled via `d3.zoom`.
