This visualization shows a world map with landmasses in teal, graticules, and country interiors outlined in a lighter shade. It uses the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render geographic features. The data is loaded from the World Atlas TopoJSON file using `d3.json` and processed with `topojson.feature` and `topojson.mesh` to distinguish land from country borders. Render is done with React in SVG, applying distinct CSS classes for land, sphere, graticules, and interiors.
