Git City 3d Github Visualization

This turns GitHub profiles into 3D pixel art buildings where your contribution count sets the height, repo count determines width, and stars control window brightness. Built with Next.js, React Three Fiber, and Supabase, it uses instanced rendering to handle lots of buildings without killing performance. The code shows how to map GitHub GraphQL API data to building metrics, set up instanced meshes for windows, and animate selections with useFrame. Good starting point if you want to visualize developer activity spatially or learn R3F patterns for data-driven 3D scenes. The compare mode for side-by-side profiles is a nice touch.
