If you have a spare hour, then feast your eyes on Geoff McGhee's video documentary "Journalism in the Age of Data," which explores the exciting potential and occasional pitfalls of modern data visualization.
There is so much data floating about that at some point it all becomes meaningless, impossible to process because we can't relate to it. It seems everyone recognizes the challenge and many have begun to create infographics to present information.
The problem is that many infographics are not infographics at all or are not very good. Bad infographics just muddy our understanding of the data.
This well-worth-your-time documentary explains data visualization and showcases some of the best work. In the end data visualization is about taking complexly large amounts of data and beautifully presenting it in a manner that makes us grasp proportions instantly.
