How to plot nodes of different shapes and facecolor of bbox in the same graph using networkx and matplotlib in Python?

I want to plot a simple graph using networkx. There are two nodes with labels Python and Programming in each. The code and graph are as follows: import networkx

Not all edges showing in AtlasView NetworkX

I have the following network graph. # Create the graph with unique edges to check the algorithm correctness G = nx.MultiGraph() G.add_edge('A','B',route='56BM',

Determine butterfly subtopologies in a network topology

I recently got a project where I have to identify all the butterfly subtopologies in a network. The network has to be implemented using a graph. Fortunately, I

python: what is a best way to find paths with x length in 2d array?

Assume that I have an array like this [[0, 1, 0, 0], [1, 0, 2, 5], [0, 2, 0, 0], [0, 5, 0, 0]] each index is a node index so [0, 1, 0, 0] means node0 has a edge

networkX: ego_graph without sibling?

I have a directed with no-cycles networkX graph. I would like to create a subgraph with only all direct or direct predecessors of a given node n. For instance,

Networkx color graph edges based on weight value

I have a dataframe with some columns. I've created a Networkx undirected graph and I want to draw the corresponding network. I need also to change the color of

How to do I get the coordinates of all points 5 kilometers away from a given node along a network in osmnx?

I have identified a node id in osmnx graph (green point on the image). What I need is to create points that are exactly 5 kilometers from the identified node al

Walk back until first branch found in networkx graph

Given a directed graph, I want to start at a leaf node, and walk back (breadth first) until I find the first node with more than one successor (or a degree grea
