## Specifications

### Aggregation

Hierarchy charts [aggregate values (metrics) for each hierarchy level (dimensions)](/data-exploration/chart/chart-common.md#dimension-metric) and render a hierarchy structure.

| Item      | Role      | Notes                                                                  |
| --------- | --------- | ---------------------------------------------------------------------- |
| Hierarchy | Dimension | Specify from higher to lower levels (e.g., Region → Prefecture → City) |
| Value     | Metric    | Used as weight if specified                                            |

#### Example Configurations

* Show "Sales composition by Region → Prefecture → City" as a sunburst
  * Hierarchy (Dimension): Region, Prefecture, City
  * Value (Metric): Sum of sales
* Show "Counts by organizational hierarchy" as a tree
  * Hierarchy (Dimension): Division, Section, Team
  * Value (Metric): None (aggregated by row count)

### Render Type Specifications

* Tree, Treemap, and Sunburst render the hierarchy as-is
* Bar (Drill Down) starts at the top level, and clicking a bar drills down to the next level
  * Specify two or more levels and set the render type to "Bar (Drill Down)"

## Tips

### Frame Feature

Hierarchy charts(Tree, Treemap, Sunburst) support the frame feature. See [Frame Feature](/data-exploration/chart/chart-common.md#frame-feature) for details.
