Interactive Data Visualization for the Web (a D3 book by Scott Murray)

seems like I will use d3 instead of gnuplot or gnumeric for even my simple graphing needs in the future. so much control in easy ways and of course that being automateble (as opposed to manually clicking in gnumeric). there might be other ways with python etc but D3 looks fun and hip and dynamic and useful for web stuff so I am sold.
I've also found http://gis.stackexchange.com to be an excellent resource for finding techniques and getting help with visualizations programming.
The ebook version will be for sale via early release very soon (hopefully within a week or so). Note that the content is still unedited and quite rough, so that's what you'll get. But of course when you buy the ebook from O'Reilly, you get lifetime updates, including of course a copy of the "final" ebook once all the editing is done, around March 2013.
Currently, only the printed, paper edition is available for pre-order. Meaning, if you click the pre-order link now, you will get a paper copy, but not until March (or so).
For the ebook, just hold on a few more days.
Thanks for your interest!
