This visualization presents a static world map that displays country boundaries alongside graticules and a sphere outline. The map uses an equirectangular projection via `d3.geoNaturalEarth1` and renders geographic features as SVG paths through `d3.geoPath`. Data comes from the World Atlas TopoJSON dataset, processed with `feature` and `mesh` from `topojson` to extract land polygons and interior borders. The React component `Marks` structures the output, with distinct styling for the sphere background, graticule grid, land masses, and country borders.
