Specs
Generated from the source: the variants in the types, the states and tokens in the CSS, and the motion patterns that apply. The grids render the real component in both themes; the numbers are measured from the page.
- States
- Keyboard focus
- Dark and light
- Every color comes from theme tokens, so it follows data-theme (and presets like Graphite) on the page or any wrapper. Contrast is checked in both themes.

Accessibility
- The chart is a figure named by its title and described by its description; the picture has a text summary.
- Tab to the chart, then arrow keys move through the data and each value is announced; Escape leaves.
- The table toggle shows the same data as a real table for everyone who can't use the picture.
Keyboard
| Key | Does |
|---|---|
| Tab | Focuses the chart |
| Left or Right arrow | Previous or next value |
| Home or End | First or last value |
| Escape | Clears the selection |
Do and don't
Do
- Use it for a few goals, each out of its own maximum.
- Keep it to four rings or fewer.
Don't
- Don't compare rings by length: inner rings look shorter at the same value.
