This example displays a world map using a natural Earth projection, with countries rendered as light green filled polygons and oceans shown in blue. It loads geographic data from the World Atlas TopoJSON dataset and converts it to GeoJSON features using the `feature` function from TopoJSON. The map is drawn in SVG with D3 v5, using `geoNaturalEarth1` for projection and `geoPath` to generate the country paths, while a separate path element outlines the sphere.
