Speeding Up the Webcola Graph Viz Library with Rust + WebAssembly

A detailed performance optimization journey for a Spotify artist relationship graph visualization using the Webcola layout library. Starting at 8 FPS, the author progressively optimized to 60+ FPS through: eliminating SVG forced reflow from getBBox() calls, replacing D3/SVG rendering with a PixiJS/WebGL canvas renderer, porting the hot computeDerivatives loop from JavaScript to Rust/WebAssembly, applying SIMD vectorization, using const generics for 2D/3D specialization, and performing CPU-instruction-level profiling via Linux perf integrated with V8. Each optimization step is documented with profiler screenshots and measurable impact, culminating in frame times averaging ~7.25ms.
