This example visualizes the topology of the contiguous United States by drawing the mesh of internal boundaries and marking junction points where three or more arcs meet. It uses the TopoJSON library to compute the mesh from the `us.json` topology file, with `d3.geo.path` rendering the SVG paths. Circles are placed at junctions by counting arc endpoints, and the transformation scales coordinates to map space using the topology's transform metadata.
