Fork of Polished World Map
This example displays a polished world map using the Natural Earth projection, showing landmasses with a teal fill, graticules, and country interiors rendered as stroked lines. It loads geographic data from the World Atlas TopoJSON, then converts it into map features using the `topojson` library’s `feature` and `mesh` functions. The visualization is built with React and D3 v5, using `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project and draw the geometries as SVG paths. The sphere background and graticule grid are styled with light gray strokes, while the land and interior boundaries use distinct teal and darker gray colors.
