A mathematician walks into a bar

Dear readers (and by "readers" I mean "mom"), it's not that I mean to talk about mathematics all the time, it's just that when Aaron takes a handful of pennies, puts them on his Magnadoodle, and draws this, the first thing I think of is graph theory. I'll be the first to point out that this isn't a simple graph because two pennies have more than one line connecting them, but the boy is only three, so let's cut him a bit of slack. Aaron himself, though, claimed it was a constellation. Is he too young for me to tell him about Hedy Lamarr?
