This example presents an interactive world map rendered as an SVG, showing country boundaries colored in teal that turn red on hover. It uses a React component with `useData` to fetch the world-atlas TopoJSON dataset and convert it to GeoJSON features via `topojson.feature`. The map applies an equal Earth projection using `d3.geoEqualEarth` and draws paths with `d3.geoPath`. A light blue sphere background is included, and hovering a country triggers a console log of its name.
