Python Type-Hierarchy to Graphviz Generator

This Python module generates a Graphviz-compatible formatted graph that represents the type hierarchy of all the classes in the specified Python modules.

Tested on Python 3.7 and 3.10.

Usage

import type_to_graphviz

# Generate a type hierarchy graph for built in classes only.
type_to_graphviz.generate_graphviz(__builtins__)

# Generate a type hierarchy graph for built in classes and for the collections
# and abstract collections modules.
import collections
type_to_graphviz.generate_graphviz(__builtins__, collections, collections.abc)

Save the output to a file or copy and paste it into an online Graphviz renderer such as WebGraphviz.

Executing the file directly will generate a graph for built in classes, and the collections, collections.abc, and datetime modules.
