Many common graph features allow python syntax to speed reporting. Returns an unused key for edges between nodes u and v. Update the graph using nodes/edges/graphs as input. If some edges connect nodes not yet in the graph, the nodes Remove all nodes and edges from the graph. The NetworkX graph can be used to analyze network structure. To create a graph we need to add nodes and the edges that connect them. . # Start the Network off by adding all the unique Nodes (text annotations), networkx / networkx / networkx / readwrite / gml.py, Uninett / nav / python / nav / eventengine / topology.py, """Builds a simple topology graph of the active netboxes in vlan.
