-## 3D/2D Visualization Architecture
+## Visualization Architecture
 
-We use Three.js for 3D models with a modular structure under `src/three/`:
+All visualizations use SVG-based 2D components organized under each feature module:
 
-- `core/Engine.ts`: Lightweight host that creates a scene, camera, renderer, shared lights, and an animation loop. It manages model lifecycle.
-- `core/types.ts`: `IModel` interface that all 3D models implement: `init(scene)`, `update(dt)`, `dispose()`.
-- `core/anim.ts`: Tiny tween scheduler for simple time-based animations.
-- `react/ThreeCanvas.tsx`: React bridge that mounts the engine in a div and registers provided models.
-- `models/CallStackAssemblyLine.ts`: First model visualizing the Call Stack as an assembly line (conveyor + lift). Exposes `pushFrame()` and `popFrame()`.
-- `models/python/PythonVM3D.ts`: 3D visualization of Python Virtual Machine internals and execution flow.
-- `models/python/MemoryProfiler3D.ts`: Interactive 3D memory heap visualization with object allocation tracking.
-- `models/python/CallGraph3D.ts`: 3D representation of Python function call relationships and execution paths.
-
-Add a new model:
-
-1. Create `src/three/models/MyModel.ts` implementing `IModel`.
-2. Import it in a page and pass an instance to `ThreeCanvas` via `models={[new MyModel()]}`.
-3. Expose imperative methods on your model (e.g., `step()`) and call them from UI buttons.
+- Each feature's visualizations live in `src/features/[module]/components/visualizations/2d/`
+- 2D components use React with SVG animations and CSS transitions
+- Interactive controls (play/pause/step/reset) are built into each visualization component
