I’ve created a force directed graph with the nodes rendered after the links.
When the user mouses over a node, a tooltip appears and disappears with mouseout.
However, this doesn’t work cosistently. Sometimes hovering over a node does not display a tooltip. However, when I hover over another node that does display a tooltip and re-hover over the node which first didn’t work, voila it works now.
This seems to be related to when many nodes are packed together, but I cannot prove this.
This is very strange behavior and trying painstakingly to debug the problem leaves me empty handed.
Any ideas what I might be doing wrong?
