I want that each edge in my directed graph contains 3 attributes:
- weight of the edge : it’s okay
- from node: ?
- to node: ?
For both (2) and (3), I want to know from which node it is to which node is goes. ( the edge attribute should be the name of the node (it is a vertice attribute that is implemented (for instance customer_ID)).
Could any of you help me?
Thank you in advance.
