A world map rendered in SVG with D3.js displays countries as light green polygons against a blue sphere, using an equirectangular projection. The visualization loads geospatial data from a TopoJSON file via the `world-atlas` package and converts it to GeoJSON features with `topojson.feature`. D3’s `geoPath` and `geoEquirectangular` generate the country outlines, while a separate path for the sphere provides the ocean backdrop. The map is static, with no interaction or animation.
