Jer Thorp, a data artist in residence at The New York Times, shows off some of his work (like this and this) and speaks about the connection between the real world and the mechanical bits we know as data. Worth your 17 minutes.
People often miss this point about data — that it's a representation of the physical world — and because of that, things like uncertainty and complexity come attached to the numbers.

Update: Don't miss the unexpected discussion around data and capitalism.
