How to add a directed edge in Tree graph? #42

Closed TimeLord2010 closed 2 years ago

TimeLord2010 commented 3 years ago

I would like to add a directed edge in a tree graph using Buchheim Walker algorithm.

This would be just a standard tree but with directed edges. Is it possible? If so, can a example be provided?

I tried to change the line: algorithm: BuchheimWalkerAlgorithm(builder, TreeEdgeRenderer(builder)), for: algorithm: FruchtermanReingoldAlgorithm(),

and it kinda worked, except that it lost the rectangular edges.

Hm the edge rendering cannot be rectangular for FruchtermanReingoldAlgorithm

I am not sure what you mean a standard tree with directed edges.... maybe you can explain to me with a photo?
