This example displays a natural Earth projection of the world map, with countries rendered in a golden color and outlined with black borders. Hovering over any country turns it white. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the map, while TopoJSON’s `feature` method extracts country boundaries from the world-atlas dataset. The SVG sphere background appears sky blue, and the CSS `:hover` rule handles the color change, with body overflow hidden for a clean layout.
