Interaction and Multiple Views

This section discusses what is possible to do with interaction, and when it is useful to use interaction in a visualization. It also discusses how to propagate interactions across multiple views.
The image below shows the Information Visualization pipeline, as discussed earlier:
Interaction can be used in all the stages mentioned above.
Interaction is particularly useful when we cannot use a single static view to represent all the data, with all the information that is needed to answer all the questions at once. It allows the visualization to be dynamic and to adapt to be able to answer multiple questions. Interaction is especially used when visualization is applied for data analysis.
