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 market shares, budget splits, traffic sources and survey answers. Values can be percentages, counts or money: the card turns them into shares of their sum, sorts them and draws the six largest, keeping any rest as a grey arc. Without a centre figure it shows the largest share. Wide frames put the ring beside the headline and legend, square ones under the headline, vertical ones stack headline, ring and legend.

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.

Field Type Description Example
title text Headline of the chart. default: Chart title Where our new signups came from in Q3
segments text Segments as label:value pairs separated by commas, semicolons or new lines, e.g. Search:42, Direct:23.

center_value text Figure in the middle of the ring, e.g. 12.4k. Empty = the largest share. 12.4k
center_label text Small label under the centre figure. new signups

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.

Make it yours

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.
