This info vis shows a really simple idea – world oil consumption. However, when you actually look at it, it becomes really difficult to decipher because the cubes are oriented differently, thus making it really hard to tell which ones are bigger and smaller. Not to mention, the smaller countries don’t even have labels. So while looking at this actually is really nice, the information you get from it is extremely lacking.
