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

The paper discusses about the importance of graphs in visualizations and how very simple properties of a graph can prove to be efficient when presenting graphical data. I feel that the authors have done a very good job by describing the various types of charts which we can use. This paper is a good read for beginners who wish to learn about the different types of charts and graphs which can be used to visualize their data.

Every graph is presented with the reasons behind using it for a particular data set. I find that this is an important point which was mentioned in the paper so that the reader can understand the usage of different graphs. The paper was also very simple to read and understand and I learned new concepts like the bar and framed rectangles and also found the position angle experiment very interesting.

The experiment that was conducted with a group of people co-relates to real life experiences and this helps the reader in remembering the ideas which are presented in the paper. I also found the framed rectangle chart very useful because it helps us present statistics using a black and white coloring without the black color dominating the white one. I thoroughly enjoyed reading the paper and would certainly extend my knowledge by reading some of the references mentioned in the paper.
