Yes, we’ve heard the feedback; Database Diagrams is back.
SQL Server Management Studio (SSMS) 18.1 is now generally available
⚠️ Latest Version Does Not Included It ⚠️
Sadly, the last version of SSMS to have database diagrams as a feature was version v17.9.
Since that version, the newer preview versions starting at v18.* have, in their words "...feature has been deprecated".
Hope is not lost though, for one can still download and use v17.9 to use database diagrams which as an aside for this question is technically not a ER diagramming tool.
As of this writing it is unclear if the release version of 18 will have the feature, I hope so because it is a feature I use extensively.
From Object Explorer in SQL Server Management Studio, find your database and expand the node (click on the + sign beside your database). The first item from that expanded tree is Database Diagrams. Right-click on that and you'll see various tasks including creating a new database diagram. If you've never created one before, it'll ask if you want to install the components for creating diagrams. Click yes then proceed.
As of Oct 2019, SQL Server Management Studio, they did not upgraded the SSMS to add create ER Diagram feature.
I would suggest try using DBWeaver from here :

I am using Mac and Windows both and I was able to download the community edition and logged into my SQL server database and was able to create the ER diagram using the DB Weaver.
