This world map displays country boundaries and graticules using a natural Earth projection, with landmasses filled in teal and interior borders in a lighter shade. The visualization is built with React and D3 v5, using `geoNaturalEarth1` and `geoPath` to render SVG paths, while `geoGraticule` generates the latitude/longitude grid. Data comes from World Atlas TopoJSON, processed via TopoJSON’s `feature` and `mesh` functions to extract land polygons and country interiors. Styling emphasizes a clean, polished aesthetic with muted colors and hidden page overflow.
