A world map rendered with D3's geoNaturalEarth1 projection presents countries in light green against a blue sphere. The visualization loads country boundaries from the world-atlas TopoJSON and TSV files, using d3.geoPath to generate SVG paths. Interaction is handled via D3's zoom function, which applies a scale and translate transform to the map group on zoom events, while a CSS :hover rule turns countries red when moused over.
