MultiGraphUndirected graphs with self loops and parallel edges, MultiDiGraphDirected graphs with self loops and parallel edges, Ordered GraphsConsistently ordered graphs, Converting to and from other data formats. Sometimes is useful to know the the shortest path between two nodes, we can use the function shortest_path(). Often the best way to traverse all edges of a graph is via the neighbors. nodes.items(), nodes.data('color'), Methods exist for reporting nodes(), edges(), neighbors() and degree() nodes.items(), nodes.data('color'), graph attributes which attempts to completely copy For instance we try to instanciate an undirected graph: Now to give life to the network we need to add nodes and edges manually or starting from an existing dataset. The link direction is used as a reference to track flow direction in the network. Returns an iterator over (node, adjacency dict) tuples for all nodes. factory for that dict-like structure. node_dict_factory, node_attr_dict_factory, adjlist_inner_dict_factory, Returns the Barbell Graph: two complete graphs connected by a path. key/value attributes.
