Are you missing the Database Diagrams from the new SQL Server Management Studio?

If you just installed the latest preview of SSMS 18.0 you might have realized that the Database Diagrams are gone. The feature is deprecated.

Download the preview here:

Scroll down to the SSMS 18.0 (Preview) and try it out, there is also improvements.

So, what to do? Remember there is a bunch of INFORMATION_SCHEMA-views you can use.
This is an example how you can do it, the example is not perfect but help you out a bit.
