This example shows a world map rendered with a Natural Earth projection, displaying landmasses in teal with graticule lines and country borders overlaid. The map is drawn as SVG paths using `d3.geoNaturalEarth1` and `d3.geoPath`, with geographic data loaded from the world-atlas TopoJSON dataset via `d3.json` and processed through `topojson.feature` and `topojson.mesh`. A React component orchestrates the visualization, applying CSS styling for the sphere, land, and boundary strokes.
