From: How do urban mobility (geo)graph’s topological properties fill a map?
Urban mobility geographical graph, (geo)graph, for the Metropolitan Region of Rio de Janeiro (highlighted area). Each node represents a traffic zone, and each edge corresponds to a flow intensity equal to or greater than the connection threshold (0.06). The element’s colors and size are proportional to the topological degree (for the nodes) and topological strength (for the edges)
