This interactive map of India displays each state as a colored SVG region, highlighting states and showing their names via tooltips on hover. Using React for the UI and D3.js for rendering, the map loads GeoJSON data from a remote TopoJSON repository and projects it with a Mercator projection. The code uses `d3.geoPath` for drawing shapes, `topojson.feature` for converting data, and a tooltip system driven by mouse events.
