OSPF Visualizer?

All:

I am a small Wireless ISP in need of an OSPF visualizer that does not cost
an arm and a leg.

I would like one that can listen to LSA's in each area and build a map of
the network.

I anticipate that I could trouble OSPF issues with such a system.

Any open source projects?

Thanks in advance,
