What is a bubble chart?

Many datasets contain two or more quantitative variables. You may be interested in how these variables relate to each other. To plot the relationship of just two such variables, usually you use a scatter plot. If you want to show more than two variables at once, you may opt for a multidimensional bubble chart.
