'Other' ER Diagrams

[Gary Richardson]

Hey,

        Has anyone done the ER diagrams that look something like this:

TableName >0--------------||-TableName
--------                          ---------
column                            column
column
column

I think they are called an 'engineering' ER, but I can't remember.  Anyway, I
have yet to find an OS app that runs under unix that does them and they are far
more useful to me than 'standard' ER charts. If someone hasn't done the layout
for this yet, I guess I'll have to :)

thanks.
