This example shows a natural Earth projection of the world map, with each country rendered as a black shape with semi-transparent white borders against a red sphere and sky-blue background. The code uses D3 v5’s `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate SVG paths, and `topojson.feature` to convert TopoJSON data from a GitHub gist into GeoJSON. A single static SVG view displays all countries without interaction.
