This visualization displays a world map using an SVG projection, with landmasses filled in teal, graticules in light gray, and country borders drawn as interior lines. The map is rendered with React and D3 v5, using `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate paths, and `d3.geoGraticule` for the grid. Geographic data comes from the World Atlas TopoJSON file, which is loaded via `d3.json` and processed with `topojson.feature` and `topojson.mesh`. A subtle sphere outline frames the map against a neutral background.
