This example visualizes global geography with a polished world map, rendering landmasses in teal, graticules as light gray grid lines, and country borders in a contrasting shade. It shows the world using a Natural Earth projection, with the sphere outline and graticule grid providing spatial context. The visualization uses React for component structure, d3.geoNaturalEarth1 and d3.geoPath for map projection and path generation, and d3.geoGraticule for the graticule lines, sourcing geographic data from the world-atlas TopoJSON dataset.
