[I want to make circular slider]

Hello everyone!

I am working on a animation website using GSAP.

But I have a difficult problem in making circular slider.

I have googled and find similar example.

But it is similar, not the same.

Above slider is not exact circular because it moves along X axis.

I want slider moving along circle, I mean X, Y axis.

I would appreciate it if anyone help me!
