bars: step 2 – learning from the web

Need to learn a little more about data handling in javascript.  Good reference from Bostock here.  Scales tutorial by Scott Murray here.

Also, some new SVG shapes like lines.  (reference) 🙂

This stat library could be useful?  http://www.jstat.org/

Success!  Now I can make charts of random walks of data, and highlight times of change 🙂
