Whatever algorithm was used to decide what point to link the tooltip to on the top scatter plot is mildly infuriating. It's impossible to get the tooltip to highlight the pink dots at the low end of the scale. I can't mouse over them, my mouse is forced to jump around it.

EDIT: Finally got the pink dots on the left to highlight, but after much maneuvering. This is a minor bug but you might want to fix it so people don't get frustrated and leave.
