I want to reveal this path. How can I do that?

So in the attached video, there's a dotted path. The mouse is moving the way I want it to be revealed. What's the best way to do that?

Best done in Ae.

Draw path with pentool.

Add stroke and set it to a dotted line.

Set keyframes for beginning and end.

Done
