This example presents a world map in an SVG using the Natural Earth projection. The visualization shows landmasses in teal, a light gray sphere, and additional graticule and interior boundary lines. It translates TopoJSON data from the world-atlas package into GeoJSON features using the `topojson` feature and `mesh` functions, which are then rendered with `d3.geoPath` and `d3.geoGraticule`. Built with React and D3 v6, the map adapts to the full browser window size.
