Power BI Scatter and Bubble Charts
Scatter charts, also known as Bubble chart, show correlations between two or three points of data. Using two points of data we consider the chart a scatter chart, when adding a third point of data then the chart will become a bubble chart. We usually use the third point for sizing, which turns the points into a circle with varying sizes based on the data in the size field.
