Frequently Asked Questions
What is a bubble chart?
A bubble chart is like a scatter plot but adds a third dimension: the size of each bubble represents an additional variable. This lets you visualize three data dimensions simultaneously.
When should I use a bubble chart?
Use bubble charts when you have three variables to compare — e.g., market share (X) vs growth rate (Y) vs revenue (bubble size), or risk (X) vs impact (Y) vs likelihood (size).
How is bubble size calculated?
The size value you enter determines the bubble radius proportionally. Larger values create larger circles.
Can I add more than 10 bubbles?
Yes — add as many data points as you need. The chart auto-scales to fit all data.
