Bubble and Scatter Plot

Creates a bubble chart which is a variation of a scatter chart. The entities displayed on a bubble chart can be compared in terms of their size as well as their relative positions with respect to each numeric axis. Since both the x and y axes of the bubble chart are numeric scales, position is an indicator of two distinct numeric values. The area of the plot depends on the magnitude of a third numeric characteristic. Bubble charts can be used in project management to compare risk and reward among projects. They can facilitate the understanding of social, economic, medical, and other scientific relationships. You can think of them as performing a visual square-root transformation on the data set.
