What caffeine does to you!
I like this information graphic because it takes something very familiar, something most of us know and drink - coffee - and tell us something about it I didn't know. And it mixes more serious informations with purely funny knowledge.
It presents a lot of informations and consists of many small parts - which makes it rather dense. But the grid and the hierarchy make sure that the viewer doesn't get lost in the informations.
The colors are very well chosen because they all have something to do with coffee - and at the same time they tie the looong graphic together. But even though it is long and has a lot of different informations, it isn't redundant. But it does have a lot of similar facts about caffeine - which makes it rather multidimensional.
In the bottom of the graphic we see a great example of how it is risky to use humor in a quite serious information graphic. Personally, I find the graphic about Hitler very, very funny - but I bet there's a lot of people around the World who wouldn't agree with me, and some might even feel offended. Especially because this graphic is not purely a funny graphic - the intend is to inform the audience of the effect of caffeine, and the funny parts are just tools to draw attention and keep the viewer reading it to the end.
The information graphic is from a very cool site called Daily Infographic (look for a recommendation of the site in the menu under "Blogs I like") or go straight to the site here
