## About

## What it does
Donut Chart Generator creates donut chart images from a title, chart data, and an optional theme. Send a `title` and a `data` array of labeled values; each item can also include a 6-character hex `color` without the `#` prefix. You can set `theme` to `light` or `dark`, and the deprecated `slices` field is still accepted as an alias for `data`, but not both in the same request.

Use `POST /download` when you want the rendered chart as a binary image. Use `POST /link` when you want a pre-signed URL back in a JSON response. In both cases, the service is built around the same chart definition, so you can generate the image once and reuse the link in emails, dashboards, reports, or internal admin tools.

This is a good fit for visualizing category splits, subscription status, survey results, or other part-to-whole metrics. For example, you can turn `Active`, `Trial`, and `Cancelled` counts into a chart with a clear title and custom slice colors, then embed the result wherever your application needs a compact summary graphic.
