Fork of Polished World Map
This example displays a polished world map with country boundaries, graticules, and a stylized color scheme. It uses React to manage the component structure and D3.js v5 via the `d3.geoPath` and `d3.geoNaturalEarth1` APIs to project and render geographic features as SVG paths. The data comes from the World Atlas TopoJSON, with country interiors and land areas extracted using the TopoJSON `mesh` and `feature` functions. Sphere outlines and graticule lines are drawn to add visual context.
