Network types

• Directed : directed network
• Undirected : undirected network
• Bipartite : bipartite network
• Multigraph : network has multiple edges between a pair of nodes
• Temporal : for each node/edge we know the time when it appeared in the network
• Labeled : network contains labels (weights, attributes) on nodes and/or edges
