This simple demo shows Svelte and d3-shape working together. The visualisation is prebaked on each deploy, but there's also an interactive JavaScript version (drag the slider, pointlessly).
Made in response to this tweet — Svelte is as general-purpose as they come, and this app's JavaScript weighs less than 5kb. (Not sure about GPU-optimised...)
