This visualization displays a world map with countries filled in light green against a blue sphere background. It uses the Natural Earth projection to render geographic boundaries from a TopoJSON file. The example relies on D3 v5’s geoNaturalEarth1, geoPath, and json functions, along with TopoJSON’s feature method to extract country geometries. A single SVG path draws the sphere, while each country is appended as a separate path element, with subtle black strokes and low stroke opacity.
