This example uses D3 version 5 and the topojson library to render a world map with a Natural Earth projection. It displays countries as light green filled paths with black strokes, projected onto a blue sphere using the `geoNaturalEarth1` projection and `geoPath` API. The country boundaries are loaded from the world-atlas GeoJSON file and converted to geographic features via the topojson `feature` function. The visualization demonstrates basic choropleth-free mapping with static SVG output.
