Timelines and Past wives

The most obvious other subject I am looking at would have to be historical timelines, and how they are portrayed in information graphics. While surfing i found www.drawingfromexperience.wordpress.com which is a blog from a compilation of authors, from artists, to doctors, keeping an eye on the world about them visually and informatively. This graph is from an image I found on the blog from a book i have not yet read, "Visualizing information for Advocacy"
