Summary
Another timeless piece by Edward Tufte. However, it is better to read it as a sequel or supplementary piece to The Visual Display of Quantitative Information rather than a standalone piece. Using principles established by Tufte in the previous book, this book adds to the topics of small multiples, colours, and space and time. It also dwells into data density through micro/macro readings. However, readers need to understand that the book discusses info viz instead of data viz.
Things I like
1. Theoretical/academic approach. The writing is refreshing for someone who has not been reading books written by academia for some time. The use of the term, 1+1=3 (originally coined by Josef Albers), to summarise a design principle on how having two elements close together creates noise in a viz, helps readers retain what they read easier than a wall of text.
2. Quality examples. The figures and diagrams used to explain the text are plenty. Many of them are historical info vizzes that may not necessarily seem out of time at first, but they may help to get you thinking creatively and get inspired. A novel take from the usual readings on using visualisation software by helping you sanitise your lens after being overloaded with computer-generated visuals.
Final Verdict: A good read for someone interested to know more about information visuals or someone who has some experience in visualisation and will like to learn more about info viz in depth.
