Example

graph python_graph {
{{
import math

sin = math.sin(value)
cos = math.cos(value)
}}

A [label="{{= value }}"];
B [label="{{= sin }}"];
C [label="{{= cos }}"];

A -- B [headlabel="sin"];
A -- C [headlabel="cos"];

}

Output

Install

pip install graphviz-py

Important: Make sure graphviz is installed! See graphviz installation instructions.

Usage

Using files

graphviz-py -Tsvg example/example.py.dot -o output.svg
graphviz-py -Tpng example/example.py.dot -o output.png

Using stdin / pipes

echo 'digraph { A -> B [label="{{= 38 * 73 }}"] }' | graphviz-py -Tsvg > output.svg

graphviz-py passes all unknown arguments to graphviz. So you can use all graphviz arguments.
