Introduction to Information Design
Show causality.
If you can do so with your visual presentation, show why something happens the way it does.

This graffic itself shows the inherent problems of displaying data on the screen.
The visual clearly explains that Napoleon's troop numbers diminished as he moved east, no big whoop. But causality comes into play when we see that the graphic also shows time, temp and geographic location: the colder it got, the more soldiers died. In addition, the graphic also shows that troops seriously dropped off when they all had to cross a river in the middle of winter.
