I've been reading graphjam for a few months now, so when i heard about this book, it was a no-brainer. The graphs, charts, maps etc. are all very well designed and look beautiful. The references are vast, and i'd be impressed if any one person understood every single one without consulting the list at the back. They range from the everybody-should-know ones (Bohemian rhapsody by pitch), to the slightly obscure (place preference of Totos by year) to the insanely detailed (spider map of rappers).
Well worth a read and would make a good present or stocking-filler.
