This example displays a clean, uncluttered world map with country boundaries and graticules. The visualization renders landmasses in teal, country borders in a lighter shade, and a subtle graticule grid, all projected using the Natural Earth projection via `d3.geoNaturalEarth1`. Data comes from the World Atlas TopoJSON, processed with `topojson.feature` and `topojson.mesh` to extract land polygons and country borders. The SVG elements are styled through CSS classes, with the React component using `d3.geoPath` to convert GeoJSON features into SVG paths.
