That's possibly true but also possibly a world without joy."
—Amanda Cox, 2013
There’s a great interview with Amanda Cox from The New York Times on visualization, some of the skills required, and where the field is headed. I like the tidbit on design below.
Design and typography do matter. It’s about hierarchy of information and how people perceive information. Done properly, that clean up work really matters. On the other hand, it’s easy to believe that it matters more than it does. If you make a fantastically interesting chart and some poor design decisions, the data will still come through. If you make a bad chart with a beautiful design, what have you done, really?
