How do I create a circular smooth line?

Hello guys! I tried to create a circular line around a circle like an outline using dot's and the expression "every 0,001 sec create dot" It works but it is very inconsistent and it looks awful. Is there any way of doing this in a smoother fashion.

I will add a photo of what I am trying to achieve approximately.

Thank You!

dop2000 I tried this method and it works. I will do some more tweaks but it's what I wanted. Thank you!

If there is anyone who needs help with this matter just PM me and I will help you.
