This world map visualizes country boundaries and land masses using the Natural Earth projection. The D3 geoPath and geoNaturalEarth1 APIs render SVG paths for land features, a sphere outline, graticules, and interior borders. TopoJSON data from the world-atlas package supplies the geographic shapes, with the mesh function generating interiors. React manages the component state and rendering, while the marks use the teal color scheme defined in the stylesheet.
