Bubble Chart

Also known as Bubble Plot

1. What is a Bubble chart?

A bubble chart displays the relationship between 3 different numeric variables in the form of bubbles. The horizontal and vertical position of the chart shows the value of 2 numeric variables. The other variable is represented by the size of the individual bubbles.

When to use a Bubble chart?

• Consider using a bubble chart when you have 3 numerical variables: one is represented by the X-axis, one by the Y-axis, and one by the dot size.

• A bubble chart is great at showing the relationship between 2 variables with additional information from another variable.

2. How to build a Bubble chart with example

The bubble chart offers a visual representation of the relationship between cost, profit, and revenue, with each bubble representing a data point. The size of the bubble indicates the revenue, while the horizontal and vertical positions represent the cost and profit respectively, providing a comprehensive view of how these variables interrelate and aiding in identifying patterns or outliers within the data.
