A world map is rendered using D3.js, with countries filled in light green against a blue sphere. The example demonstrates a basic geographic visualization workflow, loading TopoJSON data from the World Atlas and converting it to GeoJSON features. The code uses `d3.json`, `d3.geoPath`, `d3.geoNaturalEarth1`, and the TopoJSON `feature` method to project and draw the paths as SVG elements. The map is static, showing only country boundaries and the projected Earth sphere.
