The circle primitive creates circles surfaces using the [geometry][geometry]
component with the type set to `circle`.

## Example

```html
<a-scene>
  <a-assets>
    <img id="platform" 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:

```html
<a-circle rotation="-90 0 0"></a-circle>
```
