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 (4.7E-5). The element’s colors and size are proportional to the topological degree (for the nodes) and topological strength (for the edges)
