This world map shows country boundaries projected with the Natural Earth projection, using a light gray sphere background, teal landmasses, and graticule lines. The visualization loads geographic data from the world-atlas TopoJSON file via d3.json, then converts it to GeoJSON with topojson.feature and topojson.mesh. React renders the SVG elements, while d3.geoPath and d3.geoNaturalEarth1 handle projection and path generation, with d3.geoGraticule drawing the latitude and longitude grid.
