This example uses D3.js to project world countries onto a natural Earth projection, rendering them as orange SVG paths with a steel-blue sphere background. It loads GeoJSON data from the world-atlas TopoJSON file via `d3.json` and converts it with `topojson.feature`. The visualization then applies `d3.geoPath` with `geoNaturalEarth1` to draw each country, highlighting the geographic layout without interactive features.
