Description: I did this one back in 2010, after coming back from an Edward Tufte seminar.  Having found an appreciation to Minard's Napoleon's  March visualization from 1869 (who wouldn't after having Tufte describe the elegance of the visual), I decided to see how far I can achieve it within Tableau 5.2 by means of dual axes and data manipulation.
