This interactive SVG world map visualizes country boundaries and landmasses using D3.js geo APIs, including `geoNaturalEarth1` for projection, `geoPath` for rendering, and `geoGraticule` for the graticule grid. The map is built with React, loading TopoJSON data from the world-atlas package, and displays land in teal, graticules in light gray, and interior boundaries in a contrasting shade. The sphere outline and graticules add a polished cartographic style to the visualization.
