 ``pyreverse`` analyzes your source code and generates package and class diagrams.

+It supports output to ``.dot``/``.gv``, ``.puml``/``.plantuml`` (PlantUML) and ``.mmd``/``.html`` (MermaidJS) file formats.
 If Graphviz (or the ``dot`` command) is installed, all `output formats supported by Graphviz <https://graphviz.org/docs/outputs/>`_
 can be used as well. In this case, ``pyreverse`` first generates a temporary ``.gv`` file, which is then
 fed to Graphviz to generate the final image.
