Entity-Relationship Diagram Software [closed]

Question

I saw this E-R diagram in an answer on Stack Overflow:

Does anyone know which software was used to create it?

I use LucidChart but that output is really nice!

Answer 1

Perhaps unsurprisingly, you're not the first person to be intrigued by the fancy, fancy pictures in that post. If you look at the comments section below, you can see user @dangerousdave asks...

nice diagram, what tool did you use?

...to which the poster @joel-brown replies...

... I use Visio with custom smart shapes that I built to use the James Martin ERD visual convention and a custom line pattern that gives it a hand-drawn look.

You might try reaching out to Joel at his public contact info and asking if he's willing to share the extensions he used ^{(although the original post is around ~6 years old at the time of this writing so don't be too disappointed if he's using something else by now)}.
