This example uses D3 v5 and TopoJSON to render a natural Earth projection world map. It draws a blue sphere outline via a `geoNaturalEarth1` projection and `geoPath`, then loads country boundaries from the world-atlas 110m TopoJSON dataset. Each country is appended as an SVG path with a light green fill and black stroke, while the sphere is colored dark blue. The map is static and demonstrates basic geographic data loading, projection, and SVG rendering.
