This visualization displays a zoomable world map with countries colored in light green and outlined in indigo, with a sky-blue sphere background. Countries turn maroon when hovered. The map uses D3’s `geoEquirectangular` projection and `geoPath` to render geographic features from a TopoJSON dataset (`world-atlas@2`), while `d3.zoom` enables panning and zooming. The SVG output is styled via CSS class selectors, and the map data is loaded asynchronously using `d3.json` and processed with `topojson.feature`.
