This example displays a world map rendered as SVG paths, showing landmasses in teal with country borders in darker teal, overlaid on a graticule grid and pale sphere background. It uses D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` to generate the geometric shapes, with TopoJSON `feature` and `mesh` extracting land and interior boundaries from the world-atlas dataset. The React component `Marks` maps each land feature to a path element, while the sphere and graticules are drawn first as base layers.
