generically, thats known as ERD, Entity-Relationship-Diagram. there's
ots of tools that do it, but I've never seen one that didnt make a
rather messy graph of anything more complex than a few tables.

DBVisualizer is one such tool.  Also, many UML tools can reverse
engineer a database and generate graphics, and even let you modify the
schema graphically.

the free tools I've seen have been pretty klunky and/or limited, the
decent tools tend to be commercial and range from modest to rather
expensive.
