High interactive graphics in statistics (e.g., GGobi, CCMap)
involves a lot of linking between plots in order to provide users with
better insights about the data.  However to implement this feature
effectively requires a special technique.  Model-View-Controller, and
more recently Model-View-Presenter, are two very popular interactive
software paradigms that are particularly suited to the job, and their
success are largely attributed to this fundamental idea.

This talk is split into two parts.  The first aims to provide an
introduction to this special technique, while the second part gives an
overview of Taligent's MVP, the first and foremost, yet the least
understood version of the paradigm.
