Tool for viewing network database.

Hello.

We have a database where the two main tables describe a network of nodes, like this:

A table 'nodes' describes the data for each node in the network and a table 'connections' describing how each node is connected to the other nodes.

table 'nodes' having primary key 'node_id' table 'connections' having primary key 'id' and foreign key columns 'parent_node_id' and 'child_node_id', each wich references a node id.

Is there a tool out there for viewing such a structure graphically and drilling down into the node data?

Regards,
