StreamgraphProv1.0.0
Layers stacked around a centre line in ink fills and patterns, binned so ranges morph smoothly, labelled where they're thick, with hover that isolates a layer and milestones you add by clicking a day.

Installation
pnpm dlx shadcn@latest add @beautiful-ui-pro/streamgraphNeeds your registry key. Your components.json style picks the Base UI or Radix build: radix-*, new-york and default get Radix, base-* gets Base UI.
Styles didn't apply?
The CLI adds the styles to the CSS file named in components.json (tailwind.css). Check that it points at your global stylesheet, that the project uses Tailwind CSS v4, and that the file is imported in your root layout. Installed by hand: paste styles.css into that file.
