This example renders a world map using React and D3.js, displaying landmasses and country interiors in teal on a light gray sphere with a graticule overlay. It loads TopoJSON data from the world-atlas package, then employs `d3.geoNaturalEarth1` projection, `d3.geoPath`, and `d3.geoGraticule` to generate SVG paths within a React component. The `topojson` library's `feature` and `mesh` functions extract land and interior boundaries from the topology data.
