This visualization displays a global world map using the equirectangular projection, with countries rendered as individual SVG paths filled in brown and outlined in black. The sphere background is shaded blue, and hovering over any country highlights it in a darker orange. It uses D3 v5’s `geoPath` and `geoEquirectangular` functions together with TopoJSON’s `feature` method to convert country boundaries from the world-atlas dataset. The map is drawn entirely with SVG elements, and interactivity is handled by CSS hover selectors.
