This visualization displays the state boundaries of Andhra Pradesh, India, using a Mercator projection rendered as SVG paths. The map is built with React and D3 v5, where topojson features are converted to GeoJSON for rendering via `d3.geoPath`. District interiors are highlighted in violet, and individual states change to red on hover. The data originates from a GitHub-hosted TopoJSON file of Indian district boundaries, loaded asynchronously through `d3.json`.
