The Problem of Information Overload
All of the techniques encounter the same physical problem : a certain amount of data is exceeded and the lack of space for representing all of the data intended for visualization.
Interactive tools can come to our aid.
Information visualization systems appear to be most useful when a user can
Modify the input data
Change the visual mapping
Manipulate the view generated
Interactions facilitate data exploration and may uncover relationships that could remain hidden in a static view

types of representation
Static representations don’t allow users to perform any type of interaction (un-modifiable view is generated

Manipulable representations allow users to manipulate, in the process that generates such as the view via zooming, rotation, panning, etc
Transformable representations allow users to manipulate, in the preprocessing phase, the input data of the representations, for example through data filtering
