This example displays a world map using the Natural Earth projection, with each country rendered as a green SVG path and the globe’s sphere filled in blue. It loads geographic data from a remote JSON file via `d3.json` and processes it with TopoJSON’s `feature` method to extract country boundaries. The visualization relies on D3 v5’s `geoPath` and `geoNaturalEarth1` projection to convert GeoJSON coordinates into SVG paths, demonstrating basic data binding and DOM manipulation with `selectAll` and `enter`. The map is static, with no interactive elements.
