Basic Granny Square Stitch Diagram

While preparing to teach on stitch diagrams, I was looking for the basic granny square stitch diagram but couldn't find one. This pattern is so simple that I understand the lack of need to have a diagram. Yet it is a great teaching tool. So I'm putting it here for those of you who can also make good use of it.

Other resources for crochet stitch diagrams are:
the Yarn Council of America - http://www.craftyarncouncil.com/chart_crochet.html
AND an article at dummies.com - http://www.dummies.com/how-to/content/how-to-follow-a-stitch-diagram-in-crochet.html
