The circle primitive creates circles surfaces using the geometry component with the type set to circle.
Example
<a-scene> <a-assets> <img src="platform.jpg"> </a-assets> <!-- Basic circle. --> <a-circle color="#CCC" radius="20"></a-circle> <!-- Textured circle parallel to ground. --> <a-circle src="#platform" radius="50" rotation="-90 0 0"></a-circle></a-scene> |

Parallelizing to the Ground
To make a circle parallel to the ground, rotate it around the X-axis:
<a-plane rotation="-90 0 0"></a-plane> |
