This example displays a world map using a natural Earth projection, showing landmasses in green with country boundaries. The visualization is built with React and D3 v5, using the `geoNaturalEarth1` projection and `geoPath` to render geographic shapes. It loads GeoJSON data from the world-atlas package, then uses the topojson library’s `feature` and `mesh` functions to extract land and interior borders. The map also includes a graticule grid for latitude and longitude lines, all rendered as SVG paths within a React component.
