This example shows a world map rendered as an SVG, with countries filled in green and the sphere outline in blue. It uses a Natural Earth projection to display the globe. The visualization loads geographic data from the World Atlas TopoJSON file and applies D3’s `geoPath` to generate the country shapes. The code demonstrates a straightforward pipeline with `d3.json`, `topojson.feature`, and simple SVG path elements, styling the map for clear visual separation.
