# Contribution Skyline

> A year of activity as a 3D city of bars on canvas, with real per-face shading and painter-sorted depth. Bars rise in a wave on load, the camera sways gently and you can drag to orbit. Hover any bar for its exact count and date. A stats row and legend come built in. Theme-aware, any hue.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/contribution-skyline/contribution-skyline.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/contribution-skyline
```

Registry item JSON: https://www.assembli.design/r/contribution-skyline.json (send `Authorization: Bearer <api key>`)
