How can I extract a graphical (schema) representation of an Oracle database (tables and their relationships; with colums and datatypes....). Are there (free) tools, which can do this?

I think the Oracle SQL Developer has no such feature...

You might try SQL Developer Data Modeller which does do graphical data models and is free - I don't know if it does reverse engineering though.
