This example shows a world map of countries rendered as filled green shapes with black outlines on a white sphere. It uses D3.js to load TopoJSON data from the world-atlas package, converts it to GeoJSON features via `topojson.feature`, and draws the paths with a `d3.geoPath` generator using the `d3.geoNaturalEarth1` projection. The SVG output includes a separate sphere path for the globe outline, with styling applied through the external stylesheet.
