This example displays a choropleth-style map of India, colored with the d3.scaleOrdinal and schemeCategory10 palette, with hover states that turn regions orange. The visualization uses d3.geoMercator projection, d3.geoPath for rendering, and topojson.feature to parse GeoJSON from a geoBoundaries TopoJSON file hosted on GitHub. The React-based code loads data via d3.json, appends SVG paths, and includes zoom functionality through d3.zoom, with the map heading and styling defined in HTML and CSS.
