This example displays a world map with landmasses and country borders rendered from TopoJSON data. A natural Earth projection with graticule lines shows the geographic grid, while coastlines and interior boundaries are drawn distinctly. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering, and d3.geoGraticule for the reference lines, with React managing the component structure. Spherical and land features are colored with muted teal tones, creating a clean, minimalist aesthetic.
