A natural Earth projection world map displays meteorite landing sites as red points, layered over country outlines and graticule lines. The visualization loads world geography from a TopoJSON file via `topojson.feature` and projects it with `d3.geoNaturalEarth1` and `d3.geoPath`. Meteorite coordinates from a local CSV are plotted as circles using the same projection, with `d3.select` and `.join` managing the SVG elements.
