How to create Gephi network graphics from Python?

I just found out about GephiStreamer. https://pypi.python.org/pypi/GephiStreamer

Using this package, you can send instructions from python to Gephi to create nodes and edges in Gephi.

# Create a node with a custom_property node_a = graph.Node("A",custom_property=1) # Create edge edge_ab = graph.Edge(node_a,node_b,custom_property="hello") stream.add_edge(edge_ab)

In the same way, I want to do everything in Gephi through Python. This is what I usually do.

Example:

actions:

  • load nodes

  • loading edges

  • calculate central centrality

  • resize / color nodes according to their centrality estimates

  • change the graph layout (e.g. forceatlas2)

  • specify output schedule

Below is the result that I have manually, but I want to create it by sending instructions from python to Gephi. The documentation says nothing about creating nodes, edges, and graphs.

I also found out about NetworKit. https://networkit.iti.kit.edu/data/uploads/docs/NetworKit-Doc/python/html/gephi.html

This is slightly better than gephistramer, but it requires python 3.4 or higher, and most packages like pandas, numpy or sickit are in 2.7.

There is also a way to send the file that I created in gephi back to python.

Please offer.

PS: I edited all the details of the question so that now it is easier to understand (I hope).

I found this question, looking for the answer itself. I chose Gephi as my visualizer and then wanted to build a graph that was well maintained by the tool, pulling data from my organization using Python.

I found GephiStreamer and it looks like a simple but comprehensive way to plot graphs in Gephi from an external python environment (command line or IDE),

Other options at this stage:

There is no simple answer to this. People from the Facebook group may know something, but IMO is the best way to do this is to call the Gephi toolkit , i.e. An accessible jar, from jython, check here for an example use. The fact is that jython does not allow you to install numpy and a number of other libraries, but I think you could work around this problem by connecting the output of one script to another or using a queue such as Celery.

So, I would write a script to name it graph_construction.py , which uses networkx, build a graph and then write it to standard output in gexf. Then I will write a second script, gephi.py , which will execute things in gephi and let it say a graph in pdf, and then do something like:

 python graph_construction.py | jython gephi.py output.pdf

and pray that it works.
