I just had a quick read of Getting Started with D3 by Mike Dewar.   I saw an excellent talk by the author (who works at bit.ly) related to data analysis.   Sadly, I wasn’t terribly happy with the book.   Part of it is that the book is just incredibly short!   The idea of taking MTA data to look at was good, but somehow I think more examples could have been shown, or perhaps some more involved visualizations/interactions.   After reading the book, I have a basic feeling for some of what D3 can do, but am not sure if I could have learned the same information from simply looking through the web…Some introduction to SVG would have been rather helpful.

I may play with it a bit later for a few custom visualizations and see whether it is worthwhile…From the book, and the examples that I’ve seen, it is useful when you’re wanting to do non-standard plots, otherwise, I think I’ll stick with jqplot.
