This example renders a world map using a natural Earth projection, displaying landmasses, country borders, graticule lines, and a sphere outline. The map is generated from the World Atlas TopoJSON dataset, with geographic features extracted via `topojson.feature` and `topojson.mesh`. The visualization is built with React and D3 v5, using `d3.geoNaturalEarth1` and `d3.geoPath` to project and draw the SVG paths. Styling via CSS applies a teal fill for land and neutral tones for borders and graticules.
