This example displays a world map using a natural Earth projection, with countries rendered as light green filled paths against a sky blue sphere background. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw geographic features. Country boundaries come from a remote TopoJSON source, processed through the `topojson` library's `feature` function. The sphere outline and country shapes are all drawn as SVG paths, with stroke opacity providing subtle border distinction.
