This example displays a choropleth-style map of Telangana State, India, with district boundaries drawn in black and fill colors that change to grey on hover. It uses React for component structure and D3 v5’s `geoMercator` projection with `geoPath` to render the SVG paths, while TopoJSON’s `feature` and `mesh` functions parse the district boundary data from a remote Telangana JSON file. The map is titled “Telangana State” and appears centered in a fixed 960×500 viewport, demonstrating a basic interactive state-level geographic visualization.
