Bubble Diagram
A packed bubbles diagram is good for displaying the relevance or impact of particular data via the size and color of circles. Dimensions define the individual bubbles, and measures define the size and color of the individual circles. Sales data or wealth management applications are common examples.

Bubble diagram accepts one Source and one Measuredata. You can also select a Group to separate the Source data accordingly.

Please note that the Measure needs to contain numeric fields and remember to select an Expression for the Measure field by clicking on the field first and then choosing from the drop down.
