This example renders a world map using the Natural Earth projection, displaying country boundaries and graticule lines. The visualization shows landmasses filled with a teal color, country interiors outlined, and the sphere background in light gray. The code uses React for component structure and d3-geo functions like `geoNaturalEarth1` and `geoPath` to project and draw geographic features. TopoJSON data from the world-atlas package is loaded and converted to GeoJSON using `feature` and `mesh`.
