Hi couchand, Thank you very much for sharing your thoughts on the book. It's really gratifying when someone takes the time to seriously consider an author's work and then takes the additional time to compose a thoughtful critique. It seems pretty clear that the book you wanted to read was not the book that I've written, but that's actually a pretty good thing. Your comments will definitely help me clarify the goals and approaches of the book when I flesh out the Introduction. (As most everyone probably knows, the Introduction is the last section that's written. What's there now is mostly just a placeholder; I'll write the real Introduction once the editorial and technical review are complete.) If you're interested, you can check the online version in a month or so to see how effectively the book meets its own goals. For those folks that do want a book mostly devoted to D3.js, you probably won't be satisfied with my book. (In fact, the publisher and I had quite a bit of discussion about including any material on D3 at all. We finally concluded that any book on JavaScript data visualization couldn't ignore D3, so there is a chapter dedicated to the library.) The good news, though, is that you have lots of other options. Amazon lists at least nine books dedicated to D3. As an author myself, I don't feel comfortable making specific recommendations publicly (as that might imply a negative opinion of books not recommended), but anyone is welcome to contact me privately for my thoughts. (Contact info is in a comment below.) Stephen
