This example renders a world map using the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`. It displays land masses in teal, country borders as interior lines, graticules, and a light-gray sphere background. The SVG is built with React, while D3’s `geoGraticule` generates the latitude/longitude grid and TopoJSON’s `feature` and `mesh` methods extract geometries from the world-atlas dataset.
