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
