Bubble chart with three data dimensions (Transaction Date, Amount, and Discount)
Bubble chart with four data dimensions (Transaction Date, Amount, Discount, and Customer Number)
Bubble charts communicate the raw count, frequency, or proportion of a variable. Bubble size reflects quantity, bubble color reflects category, and the x and y axes both display independent values.
Use bubble charts when you are working with three data series that each contain a set of values. You can add an optional fourth variable for categorization. The bubble size is effective for emphasizing specific values and comparisons between categories.
When designing bubble charts, use clear and visible labels as these charts require clear labeling to help interpret the visualization.
