This example displays a world map rendered in an SVG using the Natural Earth projection. It loads country boundaries from a TopoJSON file via `d3.json` and converts them with `topojson.feature`. The code applies `d3.geoPath` and `d3.geoNaturalEarth1` to draw both a sphere outline and country shapes, which fill with pink and brighten to maroon on hover through CSS. The visualization demonstrates basic geographic data mapping with straightforward styling.
