PyGraphviz is a Python interface to the Graphviz graph layout and visualization package. With PyGraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms. PyGraphviz is independent from NetworkX but provides a similar programming interface.

Quick Example

>>> import pygraphviz as pgv
>>> G=pgv.AGraph()
>>> G.add_node('a')
>>> G.add_edge('b','c')
>>> G
strict graph {
        a;
        b -- c;
}

To load a dot file use

>>> G=pgv.AGraph("file.dot")
