Reaction : A Review of Overview+Detail, Zooming, and Focus+Context Interfaces

This paper extensively discusses about different types of visualizing schemes. They are,
Overview+detail interface: Here the data that designer wants to represent is done in a very detailed manner.
Zooming: the advantages of zoom while cognition of visualization. Though easy to implement, it requires lot of cognition from the user, as once zoomed in, the user has to keep track of where he is, in terms of navigation.
Focus + context: As the name suggests this is more about focusing on specific information based on the context.
Cue: This scheme concentrates on minimizing the size by modifying the data.

The description about panning and scrolling and the advantages of above methods over it is very well explained. The above mentioned schemes are sometimes not of any help when used alone. When used together they serve the purpose of better visualization. I found that there is a lot of overlap between the visualization schemes that the author categorized. The examples that the author provides are very fresh and closely relate with the current day application, which made my understanding of the topic much clear.The advantages and disadvantages of the schemes was well put.
