This example visualizes a world map, displaying national borders, landmasses, and interior boundaries. It uses a natural Earth projection (`d3.geoNaturalEarth1`) and renders geographic features as SVG paths via `d3.geoPath`. The visualization is built with React and loads geospatial data from a JSON file using `d3.json`, with `topojson.feature` and `topojson.mesh` processing the topology. The map is styled with contrasting fills for land, ocean, and borders, creating a clear and minimal cartographic view.
