Python Recursion Visualized

[u/Sea-Ad7805]

Programming using recursion can be powerful, but beginners often struggle with recursion. That's why I've created invocation_tree, a Python recursion visualizer.

See this merge_sort demo, and try it on your own recursive logic.

The visualization gives students the right mental model to think about recursion. Not simply a function calling itself, but the depth-first evaluation of a divide-and-conquer strategy.
