This world map visualizes country boundaries and landmasses using data from the World Atlas TopoJSON, rendered with a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`. The SVG output includes graticules drawn with `d3.geoGraticule` and interior borders styled as a mesh using `topojson.mesh`, all layered in a React component. The map emphasizes clean visual styling with distinct fills for land, ocean, and graticule lines, assembled from the `countries-50m.json` dataset.
