Visualizing data

I've been reading a lot about data visualization recently.1 Maybe it's because I'm extremely near-sighted,2 but I've never been very visual. Nonetheless, it's finally dawned on me3 that most people are and that I need to learn more about communicating visually if I'm ever going to communicate effectively in published papers, formal presentations, or classrooms. Here's a video from Alex Lundry that makes the point a lot better than I ever could.

2Even with glasses or contacts, my vision can only be corrected to about 20/40. When I visit the eye doctor and take off my glasses, I can't even tell that there's writing on the eye chart.
