How to create curved, directed, and labelled edges of a graph    
   I am using the graph_editor() to create a graph in the SageMath notebook. This is good but it does not allow me to create a curved edge, directed edge or a labelled edge. Does anyone know how to do this in SageMath? Thank you for your help.
 
 
I don't think this is possible from the
graph_editor()javascript thing. It's possible customize edges quite a bit - see http://doc.sagemath.org/html/en/refer...
