Products that do what GrandPerspective-style treemaps for the web and disk usage visualizer does

I like treemaps for visualizing hierarchical mass and density of resource usage. I've always particularly loved GrandPerspective's dense, colorful rendering, but haven't found a similar but generalized treemap that works in reactive web views across many data visualization contexts. So I built gp-treemap, a canvas-based web component that renders GP-style treemaps with millions of nodes: https://github.com/imbue-ai/gp-treemap/ If you want to give it a spin, try something like this command to visualize hierarchical disk usage: npx -p @imbue-ai/gp-treemap gpdu…

    Browser-based video compositor built on WebGPU▲5

    GitHub: https://github.com/Sportinger/MasterSelects I built this Browser-based video compositor with a GPU-first architecture. No Canvas 2D in the rendering path — video textures go in as texture_external (zero-copy), compositing runs through a ping-pong WGSL shader pipeline, and export captures frames directly from the GPU canvas via WebCodecs. 39 GPU effects, 37 blend modes, nested compositions, keyframe animation with bezier curves, vector masks, 10-band live EQ, video scopes, and AI-driven editing via GPT function calling. 13 production dependencies. The compositor,…
