Auto Generate Database Diagram MySQL

I'm tired of opening Dia and creating a database diagram at the beginning of every project. Is there a tool out there that will let me select specific tables and then create a database diagram for me based on a MySQL database? Preferably it would allow me to edit the diagram afterward since none of the foreign keys are set...
Here is what I am picturing diagram-wise (please excuse the horrible data design, I didn't design it. Let's focus on the diagram concept and not on the actual data it represents for this example ;) ):

MySQL Workbench worked like a charm.
I just backed up database structure to SQL script and used it in "Create EER Model From SQL Script" of MWB 5.2.37 for Windows.


In MySql Workbench (6.0) its possible generate one diagram based on tables created. For that you should access to the tools bar, press Model and forward Create Diagram from Catalog Objects and done!


It's awesome I used to work with mysql bench but for big databases (something like more than 300 tables) won't work very well but visual paradigm reverse database works so much better


Here is a tool that generates relational diagrams from MySQL (on Windows at the moment). I have used it on a database with 400 tables. If the diagram is too big for a single diagram, it gets broken down into smaller ones. So you will probably end up with multiple diagrams and you can navigate between them by right clicking. It is all explained in the link below. The tool is free (as in free beer), the author uses it himself on consulting assignments, and lets other people use it.
