This visualization displays a world map using a natural Earth projection, with countries rendered as filled SVG paths and a light blue sphere representing the globe. The map loads geographic data from the world-atlas TopoJSON dataset, then converts it to GeoJSON features via the topojson library’s `feature` function. The D3.js `geoNaturalEarth1` projection and `geoPath` API generate the country boundaries, which are styled with a pale fill and semi-transparent black strokes against a white background.
