Create bubble charts online for free. Visualize three-dimensional data using X-Y positions and proportional bubble sizes for correlation and cluster analysis.
What Is a Bubble chart?
A bubble chart extends the scatter plot by adding a third dimension: bubble size. Each data point is plotted on X-Y axes with its size representing a third variable. Bubble charts are powerful for showing relationships between three variables simultaneously, such as market size (bubble), growth rate (Y), and market share (X).
