Informationsvisualisierung [Information Visualization] by Dr.Silvia Miksch.
Course outline and excellent source of reading materials on information visualization.
I originally saw links to a couple of chapters on information visualization in Christophe Lalanne’s Bag of Tweets for April 2012.
Hoping for an entire book, I walked the URL path back to the pages with links to the chapters. The page I cite above.
Excellent collection of readings.
