ERD diagrams in Visio 2007

Hi.

Maybe I'm missing it but I'm running Vision 2007 and I don't see a way to create an ERD diagram.  I go to File->New but don't see an option for Database.  Is there some configuration I need to set?

Thanks in advance.

Thanks for the pointer to the site.  It turned out I didn't have professional so I didn't have the Database option under New.  Once I had that, it was great.

Thanks again for the reply.
