David does a great job explaining succinctly why we love data visualizations; they solve the information overload problem everyone has by exposing patterns and connections immediately.
Obviously, visualizing data is not a new profession. However, like many things democratized by the intertubes, it has become increasingly accessible, e.g. David only began his adventures in information beautifying a year ago.
I love data visualizer as a new profession. It’s a great combination of designer, hacker, statistician, mathematician, detective, showman and artist. I’ll bet a lot of web designers will migrate into data visualization as the tools and data sets become more standard.
Anyway, your thoughts on any of this belong in the comments.
