I have a diagram, I need the edge must be ORTHOGONAL, and not overlap, I don't care the direction of the edge.
I use layered layout algorithm, but the edges always overlap at the begin and end of the edge. I try to use MULTI_EDGE, but it can't reslove the problem.
I want to know how to configuration to avoid edge overlap.
This is a diagram data on JSON format, you can check the diagram. on https://rtsys.informatik.uni-kiel.de/elklive/json.html
