This class generates and displays images in the JPEG format that represent bubble charts.

It can be useful to show the positioning of subjects (such as companies, products, people, organizations, teams and so on) face to 2 qualities (classified according to a semantic scale) at time.

The width of the bubble allows to represent a third quality of the subject: this quality is relative to the other subjects.

An interesting use of this class is to create strategic marketing graphs in order to analyze the positioning of a company face to its competitors, taking two critical success factors at time.
