## Example

```ts
// xxx.ets
@Entry
@Component
struct CircleExample {
  build() {
    Column({ space: 10 }) {
      // Draw a circle whose diameter is 150.
      Circle({ width: 150, height: 150 })
      // Draw a circle with the diameter of 150 and red dashes. (If the width and height are different, the shorter value is used as the diameter.)
      Circle()
        .width(150)
        .height(200)
        .fillOpacity(0)
        .strokeWidth(3)
        .stroke(Color.Red)

    }.width('100%')
  }
}
