Charles Joseph Minard

While looking-up information on Tufte for the yesterday’s link post, I went searching for the famous graphic from Tufte’s book depicting Napolean’s march to Moscow, which is regarded by some as one of the best infographics of all time (and I have to agree, it’s pretty dang great). A quick Google image search also found a great graphic by the same designer, Charles Joseph Minard, this time depicting global emigration patterns, made in 1862.
I found it in the antique maps gallery from mapsandglobes.net, which is itself an amazing resource of old maps dating as far back as 1531. The maps are in super high resolution, but you may need to right-click and choose “open in new window” in order to bypass the image viewer they have in place.
