This world map visualization displays countries and landmasses using an equal-area Natural Earth projection. The SVG rendering layers a graticule, sphere outline, land polygons, and interior boundaries in muted teal and gray tones. Built with React and D3 v7, it fetches world-atlas TopoJSON data, converts it with topojson’s `feature` and `mesh` functions, and projects geometries via `geoNaturalEarth1` and `geoPath`. The map highlights relationships between countries by drawing interior boundaries where adjacent nations meet.
