Reaction:Graphical Perception: Theory, Experimentation, and Application to the Development of Graphical Methods

       This paper talks about how we try to get information from different types of graph showed to us. It lists the elementary tasks performed for understanding a graphical representation. The designers should not be focused on displaying the accurate information (" A table can do this work") but rather they should design graphs that can be perceived using finite number of elementary task,  meaning with out straining.
       The authors have well put the theories and has supported them with cool Experiments. Different types of charts have been taken as competitors and the elementary tasks performed to gather information from each one has been very clearly explained.I found it interesting that the angle and position also play role in visualizing the information and also I liked the idea of framed-rectangle charts. I believe the paper does not contain the entire list of tasks but it is really a good start.
