Select the 'Circular' option highlighted in Blue on the picture below from the HOME ribbon.

Drag your mouse pointer to adjust the size of your Circular stand. If you cannot see the stand size as you draw your stand, press F8 on your keyboard.

TIP: You can also use the arrow keys on your keyboard to specify the size of the Circular stand by pressing one of the arrow keys and then pressing the desired radius (distance from centre to circle edge).

NOTE: Even though you have drawn a Circular stand, the system thinks it is a square so it will position the stand text in an incorrect location. To fix this just move your text manually using the Blue nodes attached to it. (See Green text in picture below).
