This example displays a natural Earth projection world map using SVG paths generated with `d3.geoPath` and `d3.geoNaturalEarth1`. It renders the globe’s sphere in aqua and country boundaries as coral polygons with black strokes, loaded from a TopoJSON file via `topojson.feature`. Hovering a country turns it white. The code imports from D3 v5 modules and fetches world-atlas data from unpkg.
