PyPLAML

An extension for Manim (https://www.manim.community/) supporting class diagrams. Allows creating various types of classes (interfaces, enums, ...) and relations between them, which can be later animated using Manim interface.

There is also a parser for PlantUML (https://plantuml.com/class-diagram), which can automatically create a diagram from provided .puml file.

Requirements

• ffmpeg, https://ffmpeg.org/download.html
• graphviz, https://graphviz.org/download
• (Windows only) Microsoft Visual C++ 14.0 or newer and Windows SDK (https://visualstudio.microsoft.com/visual-cpp-build-tools/ under Desktop development with C++)

All requirements for Linux can be installed using:

sudo apt -y install python3-venv python3-dev pkg-config build-essential libpango1.0-dev graphviz libgraphviz-dev ffmpeg

If there are any problems you can also refer to Manim install guide (https://docs.manim.community/en/stable/installation.html)
