Set your compass at $r = 2$ put the center at the polar point $(2, 0)$ and draw a circle.

The above answer assumes that you have polar graph paper and a drafting compass.

If you convert to the given equation to rectangular form, you discover that it is a circle with its center a $(2,0)$ and a radius, $r = 2$

$(x - 2)^2 + y^2 = 2^2$

But I gave you the answer with the center point in polar coordinates.
