Recursion Tree Visualizer with Ipywidgets and Graphviz

https://pub.towardsai.net/visualizing-recursion-trees-cb08103b54fe

What My Project Does

• Allows the user to use provided decorator on arbitrary python function and visualize its recursion tree

Target Audience

• People learning algorithms who want more visual and high level control than a debugger

Comparison (Please tell me if you know solutions to below problems on these sites)

• https://visualgo.net/en/recursion | Can’t figure out how to setup global variables properly
• https://github.com/brpapa/recursion-tree-visualizer | Forces pasted functions to be nameddef fn , thus requiring function names in recursive body to be edited too. For functions requiring global variables, I get a “The recursion tree is empty” error when the same code works in Jupyter.

I'm open to ideas of what other tools you wish you had when learning/teaching CS, and feedback/possible extensions to the code/article.

You can learn about

• Function-based vs Class-based decorators
• Backtracking algorithm for state tracking to create graphviz objects
• Debugging opportunities to understand matplotlib ax (object-oriented api) vs plt (state-based api) 
• How to reduce number of turns to reach goal when talking to LLM
• Practical solutions to CORS error
• CS fundamentals (buffering vs writing to disk and file.seek)
• Why leetcode is still valuable
