This example displays a natural Earth projection of the world with countries filled in yellow and outlined with faint black strokes, set against a blue sphere and white background. It uses D3 v5 with `geoNaturalEarth1` for the projection and `geoPath` to render geographic features. Country boundaries are loaded from the world-atlas TopoJSON file via `d3.json` and converted to GeoJSON with the `topojson.feature` method, then drawn as SVG paths.
