That's the catch. Infographics don't lend themselves all that well to visualizing information necessary for business (or for informing the general public on *important* matters.) Data visualizations for business (or for managing any sort of operations/processes within a multitude of sectors) require the use of proven, effective means of communicating information so that important decisions can be made.

As such, in addition to Edward Tufte, I highly recommend people check out Stephen Few (an expert in the field) (www.perceptualedge.com). Stephen references best available research on human visual perception and cognition to drive much of the principles behind his visualization guidelines. Really great stuff. His books are an excellent read (i.e., very tangible), his blog posts bring about insightful discussions (as well as various forms of bickering), and the discussion forums engage a community of people ranging from newbies to advanced.

In regards to Napoleon's March, it's actually quite fascinating. In many ways, it reminds me of the Vietnam Memorial in Washington D.C. When you first enter along the memorial, the initial list of casualties is small, but as you descend further along the wall of fallen soldiers (i.e., as the US fell further into the war), the loss of life becomes staggering, rising above you and surrounding you. As you eventually progress out of the memorial (i.e. as the US begins to exit the war), the losses become fewer and eventually tapers... just as it began. Unlike many memorials which are of statues of soldiers, the Vietnam Memorial offers the viewer a momentary virtual trip among those that paid a dear price. The memorial isn't flashy (not that a memorial should be), yet it succeeds to honor and to inform.
