This example displays a world map using the Natural Earth projection, with countries rendered as orange polygons against a yellow spherical backdrop. The visualization loads geographic data from a world-atlas TopoJSON file via `d3.json`, then converts it to GeoJSON features using `topojson.feature`. The code employs `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw the map, attaching each country path to an SVG element. A blue sphere path provides the base layer, while country borders appear as black strokes.
