Chart layers

A chart layer enables you to display small pie charts or bar charts over locations in your map. It uses one dimension to identify the locations and a second dimension to create the pie or bar charts.

You can label the charts and use an expression to control their size. The info bubble displays useful information about the contents of the selected chart.
