This example displays a world map using a Natural Earth projection, with graticules, landmasses, and country boundaries rendered as SVG paths. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project geographic data loaded from the World Atlas TopoJSON file, processed via `topojson.feature` and `topojson.mesh`. React manages the component hierarchy, while the `Marks` component iterates over land features and draws the sphere, graticules, land fill, and interior borders with distinct colors.
