These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For growth posts, monthly reports and investor updates shared as GIF or MP4. Send the bars as Label:value pairs; they are scaled to the largest value and the last one is highlighted. A still format renders the finished chart.
Fields
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

|---|---|---|---|
title |
text | The main headline. default: Chart title | Signed URLs now serve most of our traffic |
values |

unit |

For static sites, Webflow, Shopify and no-code tools: put the fields in the query string and sign it with your signing secret. The first request renders the image, every later one is a redirect to the cached file. How to compute the signature.

accent and theme change per request. For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.
