This example displays a world map rendered with SVG paths, where countries are filled in light green and turn red on hover. It uses the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features from a TopoJSON file loaded from the world-atlas package. The map supports zooming and panning through `d3.zoom`, which applies SVG transforms to the map group. Country names are resolved by joining the TopoJSON data with a TSV table, enabling tooltips via appended `title` elements.
