Many-to-many mapping

[Jason]

All,

I have a 2 table database. Table1 is a list of IT
systems (ID, System_Name). Table2 is a list of
connections between the IT systems (ID_Source,
ID_Destination, Data_Type)

Many IT systems communicate to many other IT systems.
Can Visio draw a map from the information in this
database? I invisiion some sort of

Thank you!
Jason
