I wanted a visual way to teach entropy coding, so I built an interactive playground that walks through each step of Huffman compression.
The browser experience lets learners tweak inputs, inspect trees, and compare encoded sizes. A matching Python version mirrors the logic for scripting and automated tests.
Most explanations of Huffman coding are static and skip the tangible decision points inside the algorithm.
Built a dynamic visualization that constructs the tree step-by-step, surfaces frequency tables, and shows how bits are reassigned in real-time.
Used in study groups and workshops to demystify entropy coding and speed up onboarding for junior engineers.
