Don't know about career paths, but maybe you'd enjoy playing with http://d3js.org/ to visualize data in all sorts of interesting ways.

Thanks for the suggestion, I did a bit of dabbling with D3 a while back. I wonder what doors it could open if one became an expert in it.

I talked with the guy who originally created nvd3 a little while back - he apparently makes quite a lot contracting due to his d3 expertise (no hard numbers unfortunately).

Do you know what kind of projects he works on, that use d3?
