This visualization presents a world map using an equal-area Earth projection, rendered as an SVG with React. It displays country boundaries in teal against a light gray sphere, with graticules and interior lines in a subtle gray. The code employs D3's `geoEqualEarth`, `geoPath`, and `geoGraticule` to project and draw geographic features from the `world-atlas` TopoJSON dataset, while `topojson`’s `feature` and `mesh` functions prepare the country and interior geometries.
