Algorithm Visualizer is an interactive platform that helps you understand how algorithms work by visualizing them in real time. It’s ideal for students, educators, and developers who want to see algorithms in action rather than just reading code.
Live Visualization: Watch algorithms like sorting, searching, and graph traversal animate step-by-step.
Multi-language Support: Includes visualization libraries for JavaScript, Python, C++, and more.
Scratchpad Mode: Experiment with your own code and see how it behaves visually.
Open Source Ecosystem: Contributions are welcome across multiple repositories:
algorithm-visualizer: React-based frontend
server: API backend
algorithms: Prebuilt visualizations
tracers.*: Language-specific visualization libraries
You write or select an algorithm.
The platform interprets visualization commands embedded in the code.
It renders the algorithm’s behavior — like comparisons, swaps, or recursive calls — in a dynamic UI.
Makes abstract concepts tangible
Great for debugging and teaching
Encourages experimentation and learning by doing
