This visualization displays a world map with country boundaries, rendered using a Natural Earth projection with graticules and interior borders for visual polish. The map uses d3.geoPath to project GeoJSON features derived from the World Atlas TopoJSON dataset. React manages the component state and rendering, while d3’s geoNaturalEarth1 and geoGraticule define the projection and grid lines. The SVG output styles landmasses in teal with lighter graticule strokes, with country interiors highlighted for clarity.
