FlowingData explores how statisticians, designers, data scientists, and others use analysis, visualization, and exploration to understand data and ourselves.
As for me, I'm Nathan Yau and I have PhD in statistics from UCLA. My dissertation was on personal data collection and how we can use visualization in the everyday context. That expands to more general types of data and visualization and design for a growing audience.
I've also written a couple of books on how to visualize data, and the series is growing.
