Vizzy

A chart you can paste. An agent gathers the rows. You get a link and a PNG.

Not a D3 playground. Not a chart grammar. Bar, line, or scatter — taste is fixed. Copy the image into Notion, Docs, or a blog.

How it works

1. Rows plus a short source (where they came from — say so if you don't have one).
2. Share mints a page and a PNG (apps/share).
3. You pick a size when you copy. Size is an export, not a compile.

The thing people use is apps/share. That is the gallery, the paste URL, and the image.

Anybody

Type what you want on the site, or POST /api/compose with { "prompt": "..." }. You get a chart URL and a PNG. Bots that can submit a form or POST JSON can use the same door.

The local MCP (publish_chart) is still there for chats that already speak tools. Agent contract: AGENTS.md, live at https://vizzy.run/agents. OpenAPI: https://vizzy.run/openapi.json.
