bar, proportional symbols, but pie charts aren't there even in beta 2.2. Help is currently down, so you will have to wait to see the link for unsupported tools
This is not yet in ArcGIS Pro. There is an enhancement logged with technical support [ENH-000109862: Provide a functionality in ArcGIS Pro to use Pie, Bar/Column and Stacked chart information as symbology renderer for features and to be able to label the chart information.]
Thanks Dan Patterson ! Glad someone have the time and nerves to betatest. Just tried making a LYR (with PieCharts symbology) and import it to Pro. It kind-of works (no ability for fine-tuning in Pro 2.3.3).
