This example visualizes a world map using TopoJSON data, displaying countries as blue shapes with orange outlines on a pink globe background. It leverages the d3.geoNaturalEarth1 projection and d3.geoPath to render geographical paths, with the TopoJSON feature function converting the data into usable features. The map is drawn as an SVG, sourced from a GitHub-hosted JSON file, and styled via CSS classes for the globe and country boundaries.
