This world map visualization renders global landmasses and country borders using the Natural Earth projection. The code draws graticules, a sphere outline, land polygons, and interior boundaries as SVG paths via `geoNaturalEarth1`, `geoPath`, and `geoGraticule`. It loads geographic data from the world-atlas TopoJSON source, converting it with `feature` and `mesh`. The React component manages data fetching through a custom hook, while styled fills and strokes distinguish land, interiors, and grid lines.
