Design once, then paste a stable image URL into email, reports, documents, dashboards, bots, or an ordinary image tag.
The same configuration is already encoded as a cacheable SVG request. Copy it into anything that accepts an image URL.

Google sign-in adds durable chart URLs, server-rendered PNG, revocable API keys, usage totals, export, and deletion.
One configuration becomes three things: a preview you can trust, a file you can download, and a URL that renders the same image on demand.
These are not screenshots. Each one is the exact SVG the /api/chart endpoint returns for the request beside it — open it in the studio to change the numbers.

The API is intentionally small. Every request reads exactly these query parameters; anything omitted uses its default.
| Parameter | Accepts | Default |
|---|---|---|
| type | bar, line, area, or donut | bar |
| title | Chart heading, up to 100 characters | Monthly progress |
| labels | Comma-separated labels, up to 36 characters each | Jan,Feb,Mar |
| values | Comma-separated non-negative numbers | 24,38,52 |
| width | 320–1600 pixels | 800 |
| height | 240–1200 pixels | 480 |
| color | Six-digit hex accent colour | #ff7b5c |
| background | Six-digit hex background colour | #ffffff |
| grid | Draw horizontal guide lines | true |
| valuesOn | Print the value beside each point | true |
| format | svg or png | svg |
Stated up front so nothing on this page overpromises.
Yes. The studio, the downloads, and the public /api/chart endpoint work without an account. Signing in with Google adds saved charts, stable embed URLs, revocable API keys, and visible usage totals.
No. The studio runs in the browser, and the result is a portable SVG or PNG file plus an image URL. Nothing is computed at the viewer's end, so the image works in places JavaScript never runs.
Bar, line, area, and donut, each with a single series of 1 to 12 non-negative points. Stacked bars, dual axes, and multi-series grammar are deliberately out of scope.
Yes, if you save it while signed in. A saved chart keeps one short URL that always renders the latest revision, and it can be revoked at any time. Request URLs are fixed once shared.
