To play with the data yourself, get the Mondrian software and the dataset. Thanks goes to Sergej Potapov, who wrote the script to manage the data!

Here is an example of the so called "Sectioned Density Plot", which was recently published in "The American Statistician" (Vol 60, No. 2, 167-174).

Using a simple histogram, maybe with an added density estimator, and/or a simple standard boxplot for group comparison does the job here. No need to "invent" a new plot, which introduces more problems as it solves any.
Actually this plot makes a good case against the use of graphics ...

Haven't we been preaching against 3-d barcharts and the like for a long time? Here is what we didn't think of in our wildest dreams: an animated 3-d barchart!
As you might guess, this is the usage statistics from this blog over the last week. It is not hard to draw "The Good" (far less sensational)

(This statistics also tells me why my quota is used up, so I moved most of the recent stuff to another server!)

Well, the Tour de France 2006 is only a few weeks ahead, probably still time to give an update on the 2005 data.
We now have the data recompiled with drop outs (thanks to Sergej).

Interesting to see that almost half of the cyclists categorized as "sprinter" don't make it to the Champs-Elysees.

Looking at the ranks is quite funny as well. Here's what happens when you start as first and last ...
(Certainly, David Zabriskie would have probably looked better when not having the crash in the team time trial)

For those of you who do not stop by at JunkCharts regularly, here is what John S. found:

Probably one of the best example of "featurism"; computer scientists set free with no idea of application ...
