This world map displays global landmasses and country borders using a natural Earth projection. Built with React and D3 v7, it renders SVG paths via `d3.geoPath` and `geoNaturalEarth1`, overlaying a graticule grid and sphere outline. The visualization loads GeoJSON from the world-atlas TopoJSON dataset, converting it with the `topojson` library’s `feature` and `mesh` functions. Land areas are filled in teal, with interiors highlighted by a distinct stroke color.
