Visualizing Undirected Graph That’s Too Large for GraphViz? [closed]

Graphviz itself provides a solution for rendering large graphs. Namely, Graphviz includes sfdp, a multiscale version of fdp (also in graphviz, similar to neato) for the layout of large undirected graphs which has been useful for drawing large graphs (70k nodes, 500k edges) in my project. You can find documentation for this software on the … Read more

how to draw multigraph in networkx using matplotlib or graphviz

Graphviz does a good job drawing parallel edges. You can use that with NetworkX by writing a dot file and then processing with Graphviz (e.g. neato layout below). You’ll need pydot or pygraphviz in addition to NetworkX In [1]: import networkx as nx In [2]: G=nx.MultiGraph() In [3]: G.add_edge(1,2) In [4]: G.add_edge(1,2) In [5]: nx.write_dot(G,’multi.dot’) … Read more

Why is pydot unable to find GraphViz’s executables in Windows 8?

The problem is that the path to GraphViz was not found by the pydot module as shown in the traceback: ‘GraphViz\’s executables not found’ I solved this problem on my windows 7 machine by adding the GraphViz bin directory to my computer’s PATH. Then restarting my python IDE to use the updated path. Install GraphViz … Read more

Keras: “RuntimeError: Failed to import pydot.” after installing graphviz and pydot

The error message is a bit misleading, as you can see here. The problem is that graphviz is not installed. But you mention that graphviz was installed using pip. This is also misleading, since that graphviz package is just a python wrapper, and the graphviz binaries have to be installed separately for the python wrapper … Read more

pydot and graphviz error: Couldn’t import dot_parser, loading of dot files will not be possible

Answer for pydot >= 1.1: The incompatibility of (upstream) pydot has been fixed by 6dff94b3f1, and thus pydot >= 1.1 will be compatible with pyparsing >= 1.5.7. Answer applicable to pydot <= 1.0.28: For anyone else who comes across this, it is due to the changes in pyparsing from 1.x to the 2.x release. To … Read more
