Animate 2D Circle being drawn I am trying to get the effect seen in the answer for this question How do you animate the labels for a diagram in Blender? to work on a circle. I created a new curve -> Circle, set it to 2D, set fill to "none", increased the bevel depth and resolution, and then animated the bevel factor, but to no avail. How should I go about achieving this?
A Curve>Circle is not going to work for what you want to do, a circle is a closed path and you need an open one.

Create a curve and make the circle so that the start and end point of the curve are in the same place, but do not close the path.


Then animating the start or end of the bevel factor should work fine.
