Yesterday Flowing Data posted a parallel set graph illustrating the demographics (sex, age, class) of Titanic's survivors vs non-survivors. I find it very striking visually, though not necessarily intuitive to understand. Heading over to the original graphic at Jason Davies' site is more helpful as Davies explains the parallel concept and points out some of the obvious conclusions to be drawn. His chart is interactive - giving statistics that pop up as parts of the graph are moused over and allowing the viewer to toggle views to curves and icicle plots. I actually find the icicle plot version easiest to understand, though enjoy trying to wrap my mind around the parallel data. (According to the comments on the Flowing Data post, there are better uses for parallel data, and I'd be interested to see an example.)
Contrast this with the Titanic graphics Flowing Data linked to today. Posted on Infographics news by Chiqui Esteban, there are 7 illustrations of the Titanic and its sinking, many having been originally published in The Graphic. Esteban explains that the originals were published either in 1912 and/or in 1914 and explains that while they don't have today's flash and interactivity of graphics, effectively illustrate the Titanic's sinking.
