A world map visualization displays country borders and landmasses using a Natural Earth projection. The map renders land areas in teal, interior borders in a lighter stroke, and includes graticules and a sphere outline for geographic context. Built with React and D3 v5, it uses `d3.geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project shapes, while TopoJSON processes the world-atlas dataset to extract land features and country boundaries. The SVG output updates asynchronously after loading the geographic data.
