This example displays a world map rendered with the equirectangular projection, showing country boundaries as styled SVG paths. It loads geographic data from the World Atlas TopoJSON dataset and converts it to GeoJSON using the `feature` function from TopoJSON. The visualization uses D3 v5’s `geoPath` and `geoEquirectangular` to generate the map, with countries filled in a light beige and outlined with a dark stroke. The code demonstrates basic data fetching, projection setup, and DOM manipulation through D3 selections.
