# Donut

> One total, split into a few parts. Sample data: monthly recurring revenue by plan, Enterprise $82K (45%), Starter $17K (9%).

- Type 017 · Part of a whole
- Component: `<Donut>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/donut` (free in Hearth: the public registry, no token; Signal with Code and Complete)
- Type page: https://usechartory.com/charts/donut

## Installation

1. **Set up the registry once.** This chart is free in Hearth and MIT licensed: no token. Add @chartory to components.json once (the URL alone, no headers), or skip this when another chart is already installed. [Installation guide](https://usechartory.com/docs/installation)

2. **Add the chart.** One command adds the Donut component to your project.

```bash
npx shadcn add @chartory/donut
```

3. **Use it.** Pass your rows. The props are the Figma properties.

usage.tsx:

```tsx
import { Donut }
  from "@/components/chartory/donut"

<Donut
  data={mrrByPlan}
  size="m"
/>
```

## Donut chart: a React and Figma chart in four sizes

### What does a donut chart show?

A donut chart splits one total into a few slices, a full pie in Hearth and a ring in Signal, with each part's amount and share listed beside it. Use it for revenue by plan, traffic by source or any single split with four or five parts.

Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.

### What is the Donut component?

It is one **<Donut>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is two to six parts of one total.

Sizes **XS**, **S**, **M** and **L** re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.

### When should I use it?

- **Is it one moment, not a trend?** Yes means the donut fits.
- **Are there six parts or fewer?** Yes means the donut fits.
- **Do the parts sit in one level?** Yes means the donut fits.

### When does another type fit better?

- **The split over many periods.** Use Stacked bars instead.
- **Many parts in nested groups.** Use Treemap instead.
- **Parts with sub-parts.** Use Sunburst instead.

## Donut questions

### Does the Donut chart work with shadcn/ui?

Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.

### How do I install it?

It is free in Hearth and MIT licensed: add the @chartory registry URL once, no token, then run npx shadcn add @chartory/donut. The Installation guide has the steps.

### Can my coding agent install it?

Yes. Connect the Chartory MCP server and ask for the donut chart; the agent runs the same command and you review the diff.

### What data does it expect?

Two to six parts of one total. The sample data comes with the component, and the props table lists every field.

### Which sizes does it ship in?

XS, S, M and L, in Figma and in code. Each size is laid out again from the data, so text and lines keep their size.

### Is it in the Figma file too?

Yes. chart/017-pie-donut has the same properties as the component.

### Does it follow light and dark mode?

Yes. Every paint is a token, so the chart follows light and dark mode and the collection you pick.

### Which plan has the code?

None for Hearth: it is free in the public registry, no token. The Signal collection (@chartory/signal) comes with Code and Complete.
