This world map visualization renders country boundaries as green SVG paths on a blue background using the Natural Earth projection. The code fetches TopoJSON data from the world-atlas package and converts it to GeoJSON using `feature` from TopoJSON, then applies `geoNaturalEarth1` and `geoPath` from D3 v5 to generate the geographic shapes. The static map displays all countries without interactive features, relying on D3’s JSON loading and SVG selection methods to append each country path.
