AlgoVerse — Data Structure and Algorithm Visualizer
Sorting, graph and tree operations rendered as animated 3D scenes, built to make data structures legible while they run.
- Three.js
- Sorting · graphs · trees
- Vite 6
What it had to solve
Complexity is taught as notation and understood as motion. A student can recite that quicksort is O(n log n) long before they can see why the partition step is what buys it. Static diagrams show the state before and after; what is missing is the middle, and the middle is where the intuition is.
The decisions that shaped it
The algorithm drives the scene
Sorting, graph and tree operations are rendered as animated 3D scenes in Three.js, stepped by the algorithm itself rather than replayed from a recording. The visualisation is a view of real execution state, so what you watch is what the code actually did.
Three dimensions for the structures that need them
Trees and graphs stop being legible in two dimensions as soon as they have any depth — edges cross and the shape is lost. Rendering in 3D keeps the structure readable while it changes.
Step-by-step rather than play-through
Execution is exposed a step at a time so that complexity can be reasoned about at the point it is incurred, which is what makes the platform a teaching tool instead of an animation.
A modern build for a heavy client
React 19 with TypeScript on Vite 6, styled with Tailwind. A visualiser is an unusually client-heavy application, so build speed and type safety across the algorithm state carry more weight here than in a content site.
How the pieces sit together
- React 19 + TypeScript, built with Vite 6
- Three.js scenes driven by algorithm execution state
- Sorting, graph and tree operations, stepped explicitly
- Tailwind CSS
