Configuring other chart types
In this section, we will look at the last three types of built-in charts that Looker Studio offers. These are the Treemap chart, Bullet chart, and Gauge chart. Both the bullet and gauge chart types represent a single metric against an optional target value. On the other hand, a treemap chart depicts hierarchical dimension data using nested rectangles.
Treemap
A treemap chart enables you to represent a single metric for one or more dimensions. It is especially useful for displaying hierarchical data. Each dimension value is a branch represented by a rectangle whose size or area is based on the metric chosen. This rectangle or branch is further divided into multiple rectangles representing the next level dimension values and so on. Only the name of the lowest level dimension is displayed as a label in each rectangle. You can display the name of the parent dimension as the branch header by enabling this option from the STYLE tab.
