This example displays a world map using a natural Earth projection, with countries filled in light green and oceans in blue. It renders geographic boundaries as SVG paths, generated from a world-atlas dataset loaded via D3’s `json` function. The code employs `d3.geoPath` with the `geoNaturalEarth1` projection and uses the `topojson` library’s `feature` method to extract country geometries from the TopoJSON data. A static sphere outline is drawn first, followed by each country path, with stroke opacity creating subtle border definition.
