Fork of Polished World Map
This example displays a world map with country boundaries drawn from the World Atlas Topojson, using a natural Earth projection. The visualization highlights landmasses in teal and shows internal borders with a lighter stroke, while graticules are subtly rendered in the background. Built with React and D3 v5, the code uses `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to generate the SVG paths, and `topojson`'s `feature` and `mesh` to extract land shapes and interior borders from the topology.
