This example displays a world map using an Equirectangular-like natural Earth projection, with countries shaded in light green on a sky-blue ocean sphere. It renders geographic boundaries as SVG paths using D3 v5’s `geoPath` and `geoNaturalEarth1` projection, while TopoJSON’s `feature` method extracts country polygons from a remote dataset. The map loads asynchronously via D3’s `json` request and appends each country path to the SVG, with subtle black strokes highlighting borders.
