Hey everyone, I built a Python visualizer that animates your code line by line. It's free, runs in the browser, and needs no sign-up.

What My Project Does
Paste any Python function, give it inputs, and step forward or backward through it while the data structures animate: linked lists, trees, graphs, matrices, stacks, queues, heaps and recursion calls.
Target Audience
I designed this to help students and anyone practicing LeetCode or data structures who wants to actually see what their code is doing. It's a learning tool, not meant for production debugging.
Comparison
Python Tutor is the closest alternative, but it shows everything as generic boxes and arrows. This one draws real structures (an actual tree, graph or linked list), lets you scrub through the run, and has a dedicated recursion view.
Would love to hear feedback from everyone
