Data Visualization in 1919
Readers of Edward Tufte will remember this graphic from his first book:

data visualization from 1919 by Leonard P. Ayres -- American divisions in France each month
The original source of visualization, The War With Germany, A Statistical Summary, by Colonel Leonard P. Ayres, is now available as a free download from Archive.org and Google Books.

The book is filled with charts and visualizations, and while the quality of execution varies, it's amazing to see the 95-year-old work of Ayres. As Tufte observed, the book contains "several notable graphics all done by typewriter and rule."

Throughout my career at Morningstar, the Chicago-based investment research firm, I've used creative language and visual elements to explain complex investment information and ideas. This is a personal site--all opinions expressed here are my own.
