DSA Visualizer: watch algorithms run, step by step
DSA Visualizer is step-by-step playback for the algorithms you learnt without really seeing them. Pick merge sort or Dijkstra, hit play, scrub the state.
Who it's for
Students meeting data structures for the first time, teachers who want a clean visual on the projector, and interview candidates who have memorised the code but want the intuition.
What it does
Pick an algorithm — merge sort, Dijkstra, a BFS on an arbitrary graph — hit Play, and watch each step with the state highlighted. Pause, step forward, step back, change input, repeat. Compare two sorts side by side on the same data.
How we built it
Each algorithm is instrumented to emit snapshots at every meaningful step; the renderer replays those snapshots at a chosen speed so you see state transitions, not just a final answer.
