I am creating a graph that will represent a Fat Tree (https://www.researchgate.net/figure/Fat-Tree-structure-with-n-4-It-has-three-levels-of-switches_fig1_220429211). Currently, when I visually see the network I code up, the nodes are close together but I do not see a visible edge between them. How do I make …

How to add a feature to all the nodes in networkx
How to assign a number between 0-1 determining the sate of each of the neighbours. (That is in principle, each node has a number(state) associated to it! So that when I call a node; it has the information of its neighbours and their corresponding states! something like a Multi-dimmensional array in C! So that…
Highlighting the neighborhood of a node on selection
I created a graph using networkx and I am trying to plot it using bokeh. Currently, I am able to highlight the node that I clicked on, as well as the edges linked to the selected node. To reproduce the example, see the following code inspired from the official bokeh tutorial: I would like to be able to highli…
How to have different point sizes in ScatterPlotly Graph Object based on the values of a tuple?
I am trying to plot a network graph which is created using networkx. The graph is initialized using a pandas data frame which looks like below: The python code used for this purpose looks like: I consider the graph as a collection of lines and points so I use the Plotly Graph Object like below to visualize th…
igraph: get dict with nodes and corresponding attribute
I have a large igraph network and want to get some attributes of the vertices in the network. I have created a directed graph and want to run some algorithms: When I print the list it just gives me list of the authority scores of the vertices. However I would like to know which node exactly has each value. Is
Put nodes names to a graph with Networkx python
I created a graph G (network library) through the adjacency matrix A (numpy matrix) that stores the weights of the links. I also have the list of the names of the nodes but I don’t know how to assign the name to each node. How can I do? Answer You can loop over the nodes and append the label from
How to draw a networkx MultiGraph for nested data that has nested nodes with sizes as values in the dict?
I am trying to show 2 graphs that are not connected which represent the data as follows – The data is flexible in the sense that I control how it is nested/looks. The main idea is to be able to show a graph like following – There are 2 main nodes – Topic1 and Topic2 with their sizes as 50
Creating undirected unweighted graph from dictionary containing neighborhood relationship
I have a Python dictionary that looks like this: {‘Aitkin’: [‘Carlton’, ‘Cass’, ‘Crow Wing’, ‘Itasca’, ‘Kanabec’, ‘Mille Lacs’, ‘Pine’, ‘St. Louis’], ‘Anoka’: [‘Chisago’, ‘…
How to only get the shortest path with networkx (shortest_path)
first of all I am really new to python in genereal and espcially to networkx. I got a question regarding the networkx shortest_path(G,source,target) function. For a series of found positions (let´s call them x), I would like to find the shortest path to another series of found positions (let´s call them y). I…
Dash Cytoscape from python networks graph not honouring the nodes coordinates
I am trying to learn Dash Cytoscape and wanted to perform the following: generate a graph with network, apply a fruchterman-reingold algorithm to position the nodes, convert the data to the cytoscape format and display it in a Dash app. Here is the code: I am not seeing the nodes appear where they should be. …
