This visualization displays a world map using a natural Earth projection, with land masses rendered in a light purple fill on a white spherical background. The example loads GeoJSON data derived from the world-atlas TopoJSON file and uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for path generation, and `topojson.feature` for data conversion. A sphere is drawn first to provide the globe’s outline, followed by country paths. The stylesheet defines distinct colors for the sphere, land, and extra strokes, though the latter two are not actively applied in the current code.
