Hello!
This class displays bubble charts, [after having created them as .jpeg file]. 
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.
See the Example and the Class Help File before using it.
Pay attention! You need extension php_gd.dll enabled in you php.ini file to use this class.

Have a nice day :o)
