You may not know his name, but if you’re a fan of infographics, you’ve probably come across Charles-Joseph Minard’s work before. The 19th century French civil engineer is responsible for what statistician and data visualization expert Edward Tufte has deemed “the best statistical graphic ever drawn”: a flow map of Napoleon’s doomed 1812 invasion of Russia. (Tufte also sells a poster version of it.) The "Napoleon’s March to Moscow" map, published a year before Minard’s 1870 death, may be the singular work that has made the engineer famous to a contemporary audience of data visualization nerds, but it was the culmination of a long career developing an oeuvre of similarly detailed visualizations. A new book, The Minard System: The Complete Statistical Graphics of Charles-Joseph Minard, highlights the many lesser-known infographics Minard created throughout his career. Here are six little-seen Minard visualizations from the book.
