Other possibliities have been provided, but I think in a simple
representation that's actually a fine thing to do. Specifically, put a label
on the arc (like a node that has the property of being on an arc, rather than
at one end) and draw arcs from it.

Visual graph representation is a convention for making information clear. In
different situtations people do it slightly differently. (It would be easier
in a 3 or 4 dimensional format, but that's beyond the tools that people tend
to have available...)
