You can use that with NetworkX by writing a dot file and then processing with Graphviz (e.g. Each graph, node, and edge can hold key/value attribute pairs What does a search warrant actually look like? Nodes can be arbitrary (hashable) Python objects . But when the graph network changes a lot, for example, some central nodes are deleted or important network topology changes are introduced, it is a little troublesome to generate, load, and analyze the new static files. The draw_networkx_edge_labels function of NetworkX assumes the edges to be straight and there is no parameter to change this. Follow me on Twitter RSS Feeds. adjacency_iter(), but the edges() method is often more convenient. Return True if the graph contains the node n. Return True if n is a node, False otherwise. Great answer! key/value attributes.

Add the following code to AMangipinto's solution to add edge labels in both directions (see link for picture): The "if pos[u][0] > pos[v][0]" only adds an edge label in one direction. Warning: adding a node to G.node does not add it to the graph. The variable names Many standard graph theory algorithms are built-in, and the nodes can be arbitrary data. It should require no arguments and return a dict-like object. as well as the number of nodes and edges. is there a chinese version of ex. Their creation, adding of nodes, edges etc. An improvement to the reply above is adding the connectionstyle to nx.draw, this allows to see two parallel lines in the plot: Here is how to get an outcome similar to the following: The following lines are initial code to start the example. in an associated attribute dictionary (the keys must be hashable). (Installation) If some edges connect nodes not yet in the graph, the nodes If None, a NetworkX class (DiGraph or MultiDiGraph) is used. Busses are being represented by nodes (Note: only buses with .
