I have to confess to being a huge fan of Tufte though i came late to the party.
This book explores the methods and values of excellence in presenting information on change: how you represent movement, actions and ideas in a way that enlightens, informs and educates.
The book has excellent production values (what else did you expect) and is a a delight to explore. Tufte explains concepts and ideas in an engaging manner, pulling examples from hundreds of years of human history, from Hobbs "Leviathan", to abstract art of the 20th century. Amongst the pages are gems of insight from random places: be it descriptions fo magic tricks to descriptions of fish for those underwater! Brilliant.
It's interesting to read and reflect on how this is still relevant in a digital age where images can be distorted, manipulated or created on a whim. Even more than ever, the integrity of data and information has to meet these standards to be credible and effective. Powerpoint slaves, take note!
