EdgeTaggedGraph

EdgeTaggedGraph[{e1, e2, ...}] yields a graph with edges ej tagged with unique tags.

EdgeTaggedGraph[{e1, e2, ...} -> {t1, t2, ...}] yields a graph with edges ej tagged with tj.

Examples

Create edge-tagged graph:

EdgeTaggedGraph[{1 -> 2, 2 -> 3} -> {"a", "b"}]

Auto-tagged edges:

EdgeTaggedGraph[{1 <-> 2, 2 <-> 3, 1 <-> 3}]
