Reading: (Interaction) Toward a Deeper Understanding of the Role of Interaction in Information Visualization

This article appears to dive into more detail about the "overview, zoom and filter," mantra from the last two articles. It seems to decompose the actions a little better. This could be useful for fine-tuning a visualization, once a good, broad idea has been implemented following the parameters in the prior article.

At the outset, the paper separates InfoVis into two main components: representation and interaction. We've seen that elsewhere, particular in the DCog paper. It does a good job of motivating the need for interaction research, as well.
