This example renders a spherical world map inside an SVG, using a light blue sphere as the base and green landmasses with black outlines drawn on top. It shows the complete set of countries from the world-atlas TopoJSON dataset, projected with the Natural Earth projection. The code imports `geoPath`, `geoNaturalEarth1`, and the `feature` function from TopoJSON to convert the TopoJSON data to GeoJSON before drawing each country path.
