Monks...

I find myself needing to create a graph, as in a collection of nodes connected to one another by directed arcs. Despite the availability of suitable libraries in Java, I have no wish to turn away from Perl for this task. I have search CPAN and Google for a library to aid me with the following requirements but find the results to vague. Does anyone know/have any code snippets/modules that would allow me to:

• Easily create a graph data structure in memory - i.e. some form of API to add nodes and connect them using directed edges.
• Calculate the shortest (arcs are unweighted - i.e. constanst cost to traverse) distance between two arbitrary nodes.

Any suggestions are welcomed - the more ideas the better :)

Best wishes,
