This example shows a single blue sphere representing the Earth, rendered in an SVG canvas, with a natural Earth projection. The map is drawn using D3.js version 5, specifically the `geoNaturalEarth1` projection and `geoPath` generator, while the sphere outline is created with a `pathGenerator` on a `{type: 'Sphere'}` object. The code loads external TopoJSON data via `topojson.feature`, though the current implementation only logs the fetched data to the console and does not yet display country boundaries. The visualization uses static SVG paths with CSS classes for styling.
