This example renders a choropleth-style map of Indian districts using D3.js and TopoJSON. The visualization displays administrative boundaries as light green SVG paths with subtle black stroke outlines, projected using the Natural Earth projection via `d3.geoNaturalEarth1` and drawn with `d3.geoPath`. Geographic data is loaded asynchronously from a remote TopoJSON file, with the TopoJSON `feature` API extracting the district geometries. The code uses D3’s `select`, `json`, and `enter` methods to attach the projected paths to an SVG canvas.
