Which diagram type?
The diagram at https://www.simple-talk.com/iwritefor/articlefiles/1815-img33.jpg explains the syntax of the CREATE TABLE statement in Microsoft SQL Server 2012. The author calls it a railroad diagram.
I would like to draw such a diagram. The symbols in a Flowchart will work, but I do not see a way to make the flow connectors curve or even bend:
Is it possible?
