The message below was send to the VWNC list, two months ago. The english
version was put into the open repository as bundle Graphs.
Might be interesting for you?

I don't know if this can help you, but... Some times ago, during reading
book about algorithms, I had write program that implemented some graph
algorithms. 
Grpahs and solutions to problems such as shortest paths or maximum flow
can be showed graphically (HotDraw). There are such algorithms:

1.      Minimum spanning tree.
2.      Single-Source Shortest Paths (Dijkstra algorithms).
3.      All-pairs shortest paths.
4.      Transitive closure.
5.      Maximum flow (The relabel-to-front algorithm)
6.      Chromatic painting.
7.      Gamilton cycle(slow implementation).
8.      Topological sort.
9.      Is graph strongly connected, semiconnected.
10.     Is graph represent network.
11.     Is graph has cycles.

You can draw graph and apply several algorithms at once. If you change
graph all solutions will be recalculated.
Graphs can be file-saved.

Domain logic covered by tests, GUI is not.

Program has russian interface. I can translate interface, if this can be
interseted to anyone.
