And that&#x27;s something of the challenge with visualizations. Obviously some visualizations are just bad. But others are merely complex because they include a lot of information. This latter sort of visualization won&#x27;t be appropriate everywhere--like accompanying a typical newspaper story--but it might be just the thing to really dive down into data.<p>A great example of this is actually the Napoleon army graphic that&#x27;s famous for being in Tufte&#x27;s first book. It&#x27;s a great visualization of what happened as Napoleon&#x27;s army went off to Russia and returned. But what it&#x27;s showing isn&#x27;t really immediately obvious (and probably wouldn&#x27;t be even it if were redesigned in modern graphical style).
