The book is aimed at users of Processing wishing to benefit from the foundations already know (eg "Getting Started with Processing") and now a bigger visualization project at hand. The 7 steps of visualization are very good and accurately presented and explained in detail on the basis of larger examples, which are becoming increasingly sophisticated. Similarly, reference is made in the examples on each of the 7-step process. The language (English) is not too complicated, this precise and easy to read.
