I'd like to change the default bubbleplot setting with the radiusAxis set to linear to a much more defensible "area" relationship.
My first attempt was to simply transform my radiusField using the Math.sqrt function and continue using the default LinearAxis for radiusAxis. However, I couldn't figure out (in a simple fashion) how to take the square root of the entries in the field. Next, I thought I would change the radiusAxis to perform the square root tranformation, but that didn't appear to be simple. I could, of course, accomplish this by pre-transforming the radiusField in my data using the square root, but that is not elegant. Any help on this would be greatly appreciated,
