The paper evaluated seven different catagories of interaction that are widely used today. Initially the paper describe InfoVis as a combination of visualization and interaction. Throughtout the paper, the author attempts to reinforce the idea that interation is equally important as it can reveal hidden characteristics of data and make the relationship between data known to the user.
Overall, after reading the paper, I am convinced that while attractive visualization may grab the attention of the user, interaction proves to be a critical piece to having very useful visualization. Afterall, the point of InfoVis is to reduce the amount of work needed to understand data, and in combination with good visualiztion, good interaction would do just that.
