Release:

1.14

Date:

Sep 29, 2024

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 provides a similar programming interface to NetworkX (https://networkx.org).

Example#

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