In this paper, we present a user study aimed at understanding how human observers judge scatter plot similarity when presented with a large set of iconic scatter plot representations. The study intends to advance the state of the art of the use of quality measures as an exploration and discovery tool in information visualization.

In this paper, we present an empirical analysis of deceptive visualizations. We start with an in-depth analysis of what deception means in the context of data visualization, and categorize deceptive visualizations based on the type of deception they lead to. We identify popular distortion techniques and the type of visualizations those distortions can be applied to, and formalize why deception occurs with those distortions.
