Hi,
I took the liberty of changing a bit the appearance of the text popup: made the text with white, and smaller; made the border less prominent. This is particularly needed in more complicated visualizations.
Take a look: https://dl.dropboxusercontent.com/u/18323746/Tmp/roassal2-popup-before.png https://dl.dropboxusercontent.com/u/18323746/Tmp/roassal2-popup-after.png
I hope that is fine. What do you think?
