A world map displays country boundaries and graticules, rendered with a natural Earth projection from d3-geo. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to draw landmasses, interior boundaries, and the globe’s sphere, with data sourced from the World Atlas TopoJSON. React manages the component state, loading the topology via d3.json and converting it with topojson’s feature and mesh functions. Polished styling includes teal landmasses, light gray graticules, and a subtle sphere background.
