I have been listening to some podcasts on sketch noting recently, and after listening to one with Mike Rohde, I browsed and stumbled upon this one, about Data Visualization, a talk by Noah Illinski:
UIE Virtual Seminar 2012-02-02: Telling the Right Story with Data Visualizations, with Noah Iliinsky

I guess it may not be for everyone, but I would never read someone else’s written notes (I hardly ever read my own) but this gives a quick overview in an easy to consume way.
