I'm glad to see other people working on this problem. We (Wolfram|Alpha) are doing this too, starting out with the making the 'easy cases' nearly automatic.

Here's a blog-post describing our effort: http://blog.wolframalpha.com/2012/02/09/launching-a-democrat...

You can also play around with our examples without having to sign up to Wolfram|Alpha Pro. My favorite is an automatic analysis of the Titanic data that nicely illustrates that while the motto "women and children first" applied, being rich certainly helped: http://www.wolframalpha.com/input/?i=+&examplefile=1&...

We cover other kinds of simple analysis and visualization too, like heat maps, Venn diagrams, graphs, and so on. As always, feedback welcome.
