How to create E-R diagram in mysql

I am using MySQL. There are 28 tables in my database. I've tried to use MySQL Workbench to create E-R diagram. As there are 28 tables, everything is messed up in diagram using MySQL Workbench. Is there any way to create E-R Diagram which shows all relations properly between 28 tables??
