This visualization displays a world map using an equal-area natural Earth projection, with countries rendered as light green filled paths and the globe’s sphere filled in sky blue. It loads geographic data from a remote TopoJSON file, converts it to GeoJSON features via the `topojson.feature` API, and projects them using `d3.geoNaturalEarth1` and `d3.geoPath`. The map is drawn as SVG elements, with a stroked outline for each country and a semi-transparent border.
