Bubble
Abstract
Use when you want to show magnitude.
A bubble chart shows three dimensions of data.
Each bubble represents a data point with 3 variables. Variable 1 and variable 2 determines the bubble's location on the horizontal and vertical axis. Variable 3 determines the bubble's size.
A bubble chart is similar to a scatter plot where a third variable is added to determine the size of the bubbles.
