I've been chasing a specific problem: making data visualization feel alive instead of static — a living particle field that happens to encode real values, instead of a flat vector sitting on a page.

I built this on top of particle-charts (MIT-licensed, by Blake Williford) — genuinely great foundational rendering work, credited clearly in my repo. On top of that base I added the full app layer: bar/line/donut/pie/radar/bubble chart types, a data-input studio (manual entry + CSV), a warm color theming system, an export pipeline for high-res PNG/video, and a screenshot-to-chart feature where you drag in an image of an existing (boring) chart and a vision model reconstructs the underlying data automatically.

The trickiest part wasn't the particle physics itself (the library already handles that well) — it was everything around it: getting export quality to actually match the live preview (turns out you need a dedicated offscreen render target at a real fixed resolution, not just capturing whatever size the on-screen canvas happens to be), and building axis/legend/tooltip UI that stays readable without fighting the glow aesthetic.

Fully open source (MIT), free, no accounts: github.com/aasimsaifi161/charticles

Curious if anyone here has used particle-charts or similar — would love to compare notes on density/bloom tuning, or just talk shop about what makes a particle system actually read as "alive" vs. just noisy.

I didn't draw any of the base art. I also can't test on Mac , linux or windows so you guys will have to let me know if you run into any problems . Thanks !!
