Chernoff Faces to Display Baseball Managers From 2007 MLB Season

Check out this lovely use of Chernoff Faces by Steve Wang of Swarthmore College. This method of visualization was developed by none other than mathematician-statistician-physicist Herman Chernoff in 1973. These faces were designed on the premise that people could easily understand facial expressions. With that in mind, Chernoff used facial characteristics to represent multivariate data.

If you like, you can make your own Chernoff faces with this R library.
