It is, David McCandless is very good at visualisations, actually portrays real data in an engaging way
I went to on of his talks at the British Museum. While his visualisations are wonderful, I found that he's pretty weak on actual data (if that makes sense).
Interesting, I guess he majors on the visuals rather than the underlying.
I met him soon after his first book came out, seemed a nice enough chap, and was certainly passionate about visualisation, got a signed copy of his book somewhere.
