It can easily be extended by third-party modules that want to add their own charting implementations. It does nothing by itself. It should only be installed if some other module requires it. See Views Charts for usage of a user-centric application as the Charts and Graphs module is a framework + collection of implementation modules (under the api folder). Please read README/INSTALL files of the implementations since their installation may involve downloading flash components or third-party libraries. Drupal guidelines does not always allow packaging those with Drupal code.
