## When to use

Radial bars are a spatial alternative to a regular Bar chart, useful when you want a visually striking comparison of a small number of categories, typically a goal-tracking dashboard tile.

## Required data shape

* **Group**: categorical property.
* **Value**: numeric property; aggregated per group.

## Configuration

| Setting   | What it does                                                              |
| --------- | ------------------------------------------------------------------------- |
| Group by  | The property whose values become the rings.                               |
| Value     | The numeric value aggregated per ring.                                    |
| Max value | An optional ceiling for the outer ring's scale. Useful for goal tracking. |

## Limitations

* Effective with 3-6 categories.
* Less precise than a regular Bar chart; use it for impressionistic dashboards rather than analysis.
