I'm a big believer in Edward Tufte's approach to the visual display of information and glad to hear of ACM’s Queue taxonomy project. Had a chance to see him speak a few years back and was most impressed by his display of poor graphic models. These are visual displays that skew, or mis-represent data in a way that mis-informs the viewer.I find having an awareness of this type of display has made me much more analytical and critical of all visual displays of data.
