This interactive world map uses a Natural Earth projection to visualize country boundaries and landmasses, rendered as bright green filled regions with blue graticules and black interior borders against a blue sphere. The D3 v5 library handles geographic projections and path generation via `geoNaturalEarth1` and `geoPath`, while React components manage the SVG rendering. TopoJSON data from the world-atlas package is loaded with `d3.json` and processed using `feature` and `mesh` to extract land polygons and country borders.
