This example displays a world map of countries rendered in light green on a blue sphere, using a natural Earth projection. It shows the geographic boundaries of nations as SVG paths, generated from a world-atlas TopoJSON dataset loaded via D3’s `json` function. The code uses `d3.geoPath` with a `geoNaturalEarth1` projection to convert geographic coordinates into screen paths, and the `topojson.feature` function to extract country features from the TopoJSON data. The sphere background is drawn as a separate path to create a globe-like visual context.
