Examples of ER-diagrams "crow's feet"?

Question

ERP

Hello.
The teacher asked to create an ER diagram using the "crow's feet" method.
To be honest, this is the first time I've heard of this. All google break, found nothing.
Could you please send examples (preferably pictures) of the same diagram?
