I see a lot of intersections of connection lines on the graph visualization. And in some cases, it should be possible to reduce the intersections by adjusting node positions.

@lutzroeder I've opened #1261 for that. I only took care of low hanging fruits. So there's surely a lot of room for improvements. Please review it if you're somehow interested in it. If not, I'll close the PR.
