This world map uses D3’s natural Earth projection to display landmasses in teal against a light graticule and sphere. The SVG marks define geographic paths for countries, interiors, and a globe outline, rendered via `d3.geoPath`. Topological data from the world-atlas package is processed with `topojson.feature` and `mesh` to derive boundaries. Built with React, the visualization updates once the JSON loads, though the initial state shows a loading message.
