I have cloned the AWS Graph Explorer on my local machine and then connected it to a Gremlin server (Started with the prebuilt Modern example). The problem here is that it shows me that the edges exist but doesn't show them on Graph.
AWS Graph Explorer v1.2.0
I've tried to explore the tool in the hope that I can find a configuration for the edges to make them appear but I couldn't find anything.
You have to double click on the node to see the specific connections for the node.
(1.7.0 version I am using now actually requires you to double click twice...)
