Hello - I am the person :) You're right of course - 6 of the 11 parts in the book are dedicated to chord diagrams. Shortly after starting the book I started exploring chord diagrams again and was enjoying creating visualisations with them a little too much. Please bear in mind that it's an early access book that I'm still working on. I can see you grabbed a copy when it was listed at 7.49 (it increases as I add more), and I have to defend it a little and say I don't believe the book is crap, just incomplete! I have been working on custom visualisations which will be working their way into the D3.js and Data is Beautiful book soon. Anyway, thank you for the feedback, I have sent an email to offer a refund, because selling the books is supposed to support further work, and I don't feel comfortable if someone feels unhappy after doing that.
