This example visualizes a world map using a natural Earth projection, rendered as an SVG in React. Landmasses are filled with a teal color and outlined in gray, while graticule lines and the sphere’s silhouette are displayed in light gray. Interiors between countries are drawn as a separate mesh in a different teal stroke. The map loads GeoJSON from the world-atlas package, processes it with `topojson` functions `feature` and `mesh`, and draws paths via `d3.geoPath` using `d3.geoNaturalEarth1`. The data originates from the United Nations World Population Prospects, though population values are not depicted.
