If you are an Excel nerd and you like visualization then YOU must have this book in your collection
An excellent thorough modern reference in visualization, I refere to several stated framework occasionally when i am conducting a project especially Jorge chart classification which i find very useful.
almost all of the transformations and cases illustrated in the book are done through Excel; which i like a lot.
although the book does not contain step by step instructions to develop these charts (and the book is not intended for that purpose anyways ); if you have a decent background in Excel you will be able to recreate most of the visuals displayed or decode the example files uploaded by Jorge in the companion site.
I begin following Jorge for years, and have a relatively decent background in Excel and VBA. I did not face any problem understanding the files attached in the companion site, the methods and formulas embedded. if i recall correctly all of the examples do not need VBA to construct but i found that I was able to re-create some using VBA routine easily.
one note though the printing quality is crap :) this is a valuable book and very practical too, with bending I noticed that some pages especially at the beginning of the book started to fall :( Jorge if there is any upcoming version please print it with another publisher.
looking forward for your next book Jorge, keep sharing and keep developing good visuals using Excel .. you are among the few people around the world that have mastered creating such beautiful meaningful art with Excel, I hope you stay motivated in this domain and publish more Excel books in the future :) I will definitely buy them all :D
