This example presents a world map rendered with D3 v5 and React, displaying countries as orange shapes with black outlines against a sky-blue spherical background. It uses the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to generate the SVG paths. Country boundaries come from the `world-atlas` TopoJSON dataset, processed with `topojson.feature` before being appended to the SVG. The visualization shows all countries at a global scale, emphasizing geographic layout over thematic data.
