Some nodes disappear at 230 services

[anrub]

Somehow nodes disappear, when the total count of visible services reaches to about 230 and if there are colored nodes (e.g. warning).
The node (the circle with label) becomes visible, if I highlight another node or connection. I attached the data JSON and screenshots of the problem.

Sample JSON: viz-bug-sample_data.json.txt

Some nodes are not visible (most of class warning):

After a highlight of other nodes, they become visible but only while dimmed:

Is the problem in the data or is it a visualisation problem/bug?
How could I research further on this bug, maybe you could point me into some direction?

Thank you very much for this fine framework and all of your efforts!

Man, that's a busy graph! That is definitely a bug in the visualization library. trafficGraphView.js is the place to start for the rendering. We know the graph was laid out appropriately since the connections are still going to the missing node, and the node is just hidden.

It's either a rendering bug, or an over-optimization of which nodes to show/hide.
