Way to get number of events inside metaball about eventdrops HOT 1 CLOSED

In order to do this, I think you would have to calculate the time distance between two data points (essentially the two circles) and if it is within X (x is a predefined distance), then you can add a text somewhere int he centre of these two nodes.

But the tricky part comes when you have different zoom levels, as this will need to taken into account. Also with the zooming, you need to have an enter, update, exit pattern on the labels as well (as the metaballs will appear and disappear) and they need to be dynamically positioned.

Not sure how accurate it will be (displaying the right number, or the number you expect). It might also make it a bit more cluttered, depending on your data.
Not sure I have the time to devote to it.
