This example displays a global landmass map rendered as an SVG, with continent interiors outlined and a graticule grid overlaid. The visualization uses d3.geoNaturalEarth1 projection and d3.geoPath for geographic shapes, while topojson's feature and mesh functions process the world-atlas@2.0.2 GeoJSON data. The map’s sphere and graticules are drawn alongside land features, all styled through CSS to distinguish ocean, terrain, and boundary elements.
