Doodle animation help

Hi there,

I’m trying to figure out how to animate a circle doodle like the one below onto my portfolio. Basically, when it scrolls into view, the doodle animates so that it looks like it’s being drawn on the page.

Is there anyone that can help me try to figure this out?

Thank you!
