This example renders a world map using a Natural Earth projection, displaying landmasses, graticules, country borders, and a sphere outline. It loads geographic data from the World Atlas TopoJSON file using `d3.json` and processes it with `topojson.feature` and `topojson.mesh`. The map is drawn with `d3.geoPath` and `d3.geoNaturalEarth1`, while React components structure the SVG output. Land areas are filled teal, borders are lighter teal, and the background sphere is light gray.
