This example presents a world map projection using the Natural Earth projection. It visualizes country boundaries and graticules, with landmasses filled in teal and a light gray sphere backdrop. The map is built with d3.geoPath and d3.geoNaturalEarth1, using TopoJSON data from the world-atlas package. React manages the SVG rendering, while the topojson library’s `feature` and `mesh` functions prepare the geographic data for display.
