This example displays a natural Earth projection map of the world, with landmasses rendered in teal and graticules drawn as light gray lines. It uses React for component structure and D3 v7’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project and draw the geographic features. The land and country boundary data come from the World Atlas TopoJSON file, with interior borders generated via `mesh` from topojson.
