This example presents a polished world map with country boundaries, graticules, and a highlighted sphere outline. It uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering SVG paths, and d3.geoGraticule for the grid lines. The map draws land features and interior borders from World Atlas TopoJSON data loaded via d3.json and processed with topojson.feature and topojson.mesh. The visualization is built as a React component, applying teal-colored land masses with subtle stroke styling for visual refinement.
