This example renders a world map using a natural Earth projection in D3 v5. It loads TopoJSON country boundaries from a GitHub gist and converts them to GeoJSON features with the `topojson.feature` API. The visualization displays a blue sphere as the globe backdrop and yellow country shapes with black strokes, drawn via `d3.geoPath` and `d3.geoNaturalEarth1`. The map is presented as static SVG paths, with styling applied through CSS classes.
