This example presents a natural Earth projection of the world map, rendered as an SVG with a light blue spherical background and green landmasses outlined in black. It loads world country boundaries from the world-atlas TopoJSON dataset via `d3.json`, converting them to GeoJSON with `topojson.feature`. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere and country paths, demonstrating a straightforward choropleth-free geographic rendering workflow.
