This example displays an interactive world map using a natural Earth projection, with countries rendered as light green SVG paths that turn teal on hover. The visualization combines world-atlas TopoJSON data with a TSV file containing country names, which are added as native SVG `<title>` tooltips. The map supports pan and zoom through d3.zoom, while d3.geoPath and d3.geoNaturalEarth1 handle geographic projections. Hover effects use CSS pseudo-classes, and the map includes a blue sphere background for context.
