Word Tree Text Wrap

[GMontgomery]

Hi, 

I want to start off by saying how great the Word Tree chart is. Interactive, fun, and very different from other visualisations available. When playing around with the demo though, I noticed a common problem for larger trees, which is that there is no word wrap implemented for arbitrarily long sentences. I have some ideas about how this might scale better. Would anyone happen to know the best way to go about feature requests/making changes to the library? Can I use the google chart for longer sentences or am I better off looking for another library to use?
