Building an interactive Python visualizer for DSA & LeetCode logic
Struggling with abstract data structure flows—like pointers, recursion, and tree traversals—is one of the biggest bottlenecks when learning DSA. To solve this, I’m actively developing a web application that turns Python code into step-by-step visual executions in real time.
Instead of trying to trace complex execution flow on paper or guessing what line of code broke your logic, the tool visualizes exactly how your variables and data structures mutate as the Python code runs.
Check out the short walkthrough video attached to see the tool in action.
The app is currently supported for Python, and I am actively refining the platform based on real usage. I’m opening up testing and looking for honest feedback on the visualization clarity and user experience so I can keep making it better. Anyone who tries it out and shares feedback will get full lifetime access to all premium features.
