3d Visualizer

This one gets you up and running with Three.js and React Three Fiber for interactive 3D web experiences. The examples cover the practical stuff: basic scenes with lighting and materials, animated objects using useFrame, loading GLB models for product viewers, and 3D data visualizations like bar charts and network graphs. There's also a product configurator example that shows how to wire up interactive color changes. The instanced mesh patterns are good to see since rendering thousands of particles is where most people hit performance walls. If you're building anything that needs to display data spatially or create interactive product demos, the code here is clear enough to adapt without digging through Three.js docs for hours.
