This example demonstrates the initial step of building a geographic map by loading world land data from the world-atlas TopoJSON dataset. The code fetches the `land-110m.json` file and logs it to the console, while an empty SVG group is positioned at the center of the frame. Using d3.json for asynchronous loading and d3.select for SVG manipulation, it sets up the foundation for future projection and path rendering, though no map geometry is drawn yet.
