A world map rendered with D3.js and a Natural Earth projection displays country boundaries in light green over a blue sphere. The visualization uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate SVG paths from TopoJSON data. Country shapes are drawn by fetching a remote world.json file via `d3.json`, then processing it with TopoJSON's `feature` method. The example demonstrates fundamental DOM manipulation by appending paths to SVG elements.
