This example shows a polished world map with landmasses, country borders, and graticules rendered using a natural Earth projection. The visualization loads geographic data from the World Atlas TopoJSON dataset, converting it with `topojson.feature` and `topojson.mesh` for display. It uses React as the framework, with D3 v5 functions like `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to draw the sphere, graticule grid, land features, and interior borders as SVG paths. The teal and gray color scheme applies visual styling to the map elements.
