This visualization uses D3.js to construct a stylized face from geographic map data. It renders a world map projected using a Mercator projection, with country boundaries drawn via `d3.geoPath`, and then overlays facial features on top. The data comes from the world-atlas TopoJSON and TSV files loaded from jsdelivr. The code sets up an SVG canvas and uses `d3.geoMercator` for projection, though the facial feature construction is incomplete in the provided snippet.
