Let's make a big face!
A world map is displayed on a blue sphere, with country polygons filled in light green and outlined in black. The visualization demonstrates basic D3.js DOM manipulation by appending SVG paths to represent the Earth’s landmasses. Using the `d3.json` loader, `d3.geoPath`, and `d3.geoNaturalEarth1` projection, the code processes `final110countries.json` TopoJSON data, converts it to GeoJSON features via the `topojson` library’s `feature` function, and renders them as SVG paths.
