How to visualize a property graph

[feliksik]

In a property graphs, edges can have properties themselves. ideally, I'd like to treat an edge as a node itself, so the 'edge label' can have outgoing edges. E.g. Node A and B and C exist, with edges e1: (A,B) and e2: (e1,C):

A ---e1--- B
      |
      |
      C

I read here that this is not natively supported, but can be simulating by making e1 a node in itself.

That works, and is sort of ok, but of course it messes up the bezier curve between A and B:

A --- e1
     /  \
    /    \
   B      C

I can imagine using some visual tricks to make it clear that (A,B) is the actual edge, and e1 just the edge label itself, e.g. by encapsulating the e1 node in a parent node E1, etc. That's fine.

But how can I make the edges (A,e1) and (e1,B) look like a single bezier curve? Or is there some other, simpler way to treat an edge as a node?

I think this extension aims to solve the problem: https://github.com/dmx-systems/cytoscape-edge-connections

Assuming there is no more 'native' solution, this can be closed.
