pygraphviz

I have a dataset that represents a kind of genealogy tree. Each node has 2 parents (except first generation, they have no parents). For a given node, its parents can be from any previous generation. For example a node in generation n, can have a parent in n-1, and another parent in n-5. A node can be parent of several other nodes. So basically, for every node I know its generation and its parents. I am trying to represent this graph keeping the nodes from the same generation in the same line. Each generation has 10 nodes, except the first one. So far I am trying the "dot" layout. When I only

After installing the latest graphviz (2.26.3) on my Windows 7 Ultimate 64bit, I receive the following error: C:>easy_install pygraphviz Searching for pygraphviz Reading http://pypi.python.org/simple/pygraphviz/ Reading http://networkx.lanl.gov/pygraphviz Reading http://networkx.lanl.gov/wiki/download Reading http://networkx.lanl.gov/download/pygraphviz Reading http://sourceforge.net/project/showfiles.php?group_id=122233&package_id=161979 Reading http://networkx.lanl.gov/download Best match: pygraphviz 1.1.dev1947 Downloading http://networkx.lanl.gov/download/pygraphviz/pygraphviz-1.1.dev1947

I have installed pygraphviz using easy_install But when i launch python i have an error: >>>import pygraphviz as pgv Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named pygraphviz >>> Using Ubuntu 12.04 and gnome-terminal. Sidharth Shah Assuming that you're on Ubuntu please look at following steps sudo apt-get install graphviz libgraphviz-dev pkg-config Create and activate virtualenv if needed. The commands looks something like sudo apt-get install python-pip python-virtualenv Run pip install pygraphviz Run terminal and check by importing and see

I'm working to learning some Python graph visualization. I found a few blog posts doing some things I wanted to try. Unfortunately I didn't get too far, encountering this error: AttributeError: 'module' object has no attribute 'graphviz_layout' The simplest snip of code which reproduces the error on my system is this, In [1]: import networkx as nx In [2]: G=nx.complete_graph(5) In [3]: nx.draw_graphviz(G) ------------------------------------------------------------ AttributeError Traceback (most recent call last) <ipython-input-3-481ad1c1771c> in <module>() ----> 1 nx.draw_graphviz(G) /usr/lib

I am trying to display a tree graph of my class hierarchy using networkx. I have it all graphed correctly, and it displays fine . But as a circular graph with crossing edges, it is a pure hierarchy, and it seems I ought to be able to display it as a tree. I have googled this extensively, and every solution offered involves using pygraphviz ... but PyGraphviz does not work with Python 3 (documentation from the pygraphviz site) . Has anyone been able to get a tree graph display in Python 3? edit (19 Jan 2019) I have updated the code to be more robust: It now works for directed and undirected

Okay, here we go... I am trying to install pygraphviz on Windows 10. There are many solutions to this problem online, but none have yet worked for me. The precise problem I'm having is with this via jupyter notebook--> [1] import networkx as nx import pylab as plt from networkx.drawing.nx_agraph import graphviz_layout [2]G = nx.DiGraph() G.add_node(1,level=1) G.add_node(2,level=2) G.add_node(3,level=2) G.add_node(4,level=3) G.add_edge(1,2) G.add_edge(1,3) G.add_edge(2,4) nx.draw(G, pos=graphviz_layout(G), node_size=1600, cmap=plt.cm.Blues, node_color=range(len(G)), prog='dot') plt.show() I get

I have GraphViz 2.32 installed in Windows 8 and have added C:\Program Files (x86)\Graphviz2.32\bin to the System PATH variable. Still pydot is unable to find its executables.
