Display bubble title in some way when bubble is highlighted

[pkraker]

When the user moves over a bubble, the bubble title is hidden to show the papers in the area. This breaks the user experience, especially with long titles and overlapping bubbles, as users want to see the title in some form at any time. A tooltip is shown after a few seconds, but this is not satisfactory. A possible solution could be jQuery tooltips as they can be immediately shown.

I would suggest that the visualization context can either be the whole search or a single selected bubble (incl. the bubble title of course)
