Interactive Data Visualization for the Web by Scott Murray.
A preview version explaining D3.
Skimming the first couple of chapters it has a number of references/examples but could use one or more editing passes.
Still, if you are new to D3, it’s free and correcting any mistakes you find will be good practice.
I first saw this in a tweet by Jen Lowe.
Update: Final ebook and print copies are now available!
