This visualization presents a world map using the equirectangular projection, rendering countries as green paths on a blue spherical background. It loads geographic data from the `world-atlas` TopoJSON dataset, which is converted to GeoJSON using the `topojson.feature` function. The map is drawn with D3 v5’s `geoPath` and `geoEquirectangular` APIs into an SVG, with static styling applied via CSS classes for the sphere and country outlines.
