This book is about how to create visualisations effectively, but author does the opposite, as it requires multiple readings just to understand simple concepts. Things that can be explained in simple language have been unnecessarily taken into complex territories. The book has certainly some good information for people who want to communicate information effectively through visualisations. But to obtain this knowledge, you would have to read, re read, re read and re read. Not that the concepts are complex, but the author decided to make it complex.
