Attribute Blocks is a new tool for visualizing multiple continuously varying attributes across a region of geospace. Most of the explanations and illustrations of the technique in this article employ climatology data sets along with results computed by a simulation driven by the data sets. However neither the method nor its implementation depend in any way on issues unique to climatological applications. The author demonstrates this in part while comparing the use of Attribute Blocks to other techniques on different types of data sets. The author describes the method, compares it to some earlier methods, illustrates several techniques it enables for locating patterns in data, and briefly discusses how its implementation employs the programmable shader facility in OpenGL.
