Thanks, Robert. I've had considered R as a possible tool for this
effort. I actually used it briefly for a data visualization course I
took a few years ago, but there's still a lot more learning I would have
to do to accomplish this. 

On the other hand, it seems every other path I've tried has a large
learning curve too, so I should give R another look.
