This example displays a world map using a Natural Earth projection. It renders each country as a filled SVG path with a light blue fill and dark stroke. The map is drawn from TopoJSON data loaded from the `world-atlas` package, converted to GeoJSON features via `topojson.feature`. The visualization uses `d3.geoNaturalEarth1` to define the projection and `d3.geoPath` to generate the SVG path data.
