This visualization displays a world map with all countries rendered in light green against a medium blue background using the Natural Earth projection. The map is drawn as SVG paths generated through `d3.geoPath` with a `geoNaturalEarth1` projection, processing TopoJSON data from the world-atlas package. Country boundaries are outlined in black, and the code fetches geographic data via `d3.json` before extracting features with `topojson.feature`. The example relies on D3 v5 and the topojson library to project and render the complete set of world nations.
