For the lines/arrows, I switched to the LinkerLine library. It's an extension of the original LeaderLine library (which is seemingly no longer maintained). It isn't really widely used but I think it should serve the purpose for us (placing the lines inside of the visualization div).
Resolves #142
The error handling is now also improved. Previously, return steps (originating from throwing the exception) were also displayed. This is no longer the case.
