I <3 the ITP Alumni list. There was a thread of reading material for information visualization. Of course, various people recommended the Tufte books. But there were 2 books that I purchased. Here is the title of the first one: Now You See It. I tried looking for information but only found the Table of Contents (TOC). Based on the TOC, I purchased it, and was pleasantly surprised.

pg 41 lists attributes of data
• length
• width
• orientation
• size
• shape
• curvature
• enclosure
• spatial grouping
• blur
• hue
• color intensity
• 2-D position
• direction of motion

Part-to-Whole and Ranking Patterns

This surprised me because the Part-to-Whole ration is one I watch out for (trained from studying the LSAT), but this is slightly different because there is a visual definition.

Anyway, buy the book if you are interested.
