The Best and Worst of Statistical Graphics

This page is dedicated to John W. Tukey, who taught us all that seeing may be believing or disbelieving,
but above all, data analysis involves visual, as well as statistical, understanding.

This Gallery of Data Visualization displays some examples of the Best and Worst of Statistical Graphics, with the view that the contrast may be useful, inform current practice, and provide some pointers to both historical and current work. We go from what is arguably the best statistical graphic ever drawn, to the current record-holder for the worst.

[See the Bad Writing Contest for examples of The Best of Bad Writing. See the ACCENT Principles for effective graphical display.]
Do you know of other examples of the Best or Worst in Statistical Graphics on the Web? Send me an email with the URL and a brief description.

The page is organized as a collection of images, along with a few of the 1000 words each may be worth and some links to original sources. To reduce transmission time, most of the images are presented as thumbnails, with links to larger originals. Click on the thumnail image or on the words "Full size".
