A world map rendered in SVG shows country borders in light green on a blue sphere, with hover highlighting in red and zoom-and-pan interaction via `d3.zoom`. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project geographic data from TopoJSON, with country names from a TSV file. Hover tooltips appear through SVG `title` elements. The code loads data from the world-atlas dataset and applies a `g` transform on zoom events.
