How ChartKit treats pie charts

Each slice label in `labels` pairs with one number in `s0`. The chart normalizes those numbers into a full circle. This page hides a second series on purpose - mixing two `s` keys into a pie is usually confusing.

If you need ranked categories instead of shares of 100%, a bar chart is often easier to read.

Use cases

Device or channel mix (mobile / desktop / tablet) for a blog summary.
Budget slices in a short report where the audience knows the categories already.
A single graphic for a newsletter blurb where you only have room for one image.

Percent-friendly legend

`valueFormat=percent` can help when slice labels are shares.

How it works

List slice names in `labels` and the matching weights in `s0` (counts, dollars, or arbitrary positive numbers).
Set `title`, turn `legend` on or off, and adjust `w` / `h` when your layout is tight.
Copy HTML or Markdown so the image loads from the same `/api/chart` URL you see in the preview.

Use with ChatGPT or Claude

Tell ChatGPT or Claude the slice names and raw numbers; ask for `type=pie` and a ChartKit URL. Many models default to bar charts unless you say “pie”.

After the model returns the link, verify slice order matches your source table before you publish.
