 * Displays the length of a process.
 *
 * @extends React.Component
 *
 * @property {number} progress - Current progress value of the process.
 * Can be from 0 to 1.

 * @property {boolean} animating - Whether component is animating.

 * Can be `basic`, `primary`, `success`, `info`, `warning`, `danger` or `control`.
 * Defaults to *primary*.
 * Use *control* status when needed to display within a contrast container.
 *
 * @property {ReactElement | (IconProps) => ReactElement} renderIcon - Function component
 * to render inside circular progress bar.
 * Expected to return an Icon.
 *
 * @property {Partial<CircularProgressBarAnimationConfig>} animationConfig - Animation configuration.
 * Optional. Can define duration, easing function and etc.
 *
 * @overview-example CircularProgressBarSimpleUsage
 * Default CircularProgressBar status is `primary`, size is `medium` and animating is `true`.
 *
 * @overview-example CircularProgressBarSizes
 * To resize CircularProgressBar, a `size` property may be used.
 *
 * @overview-example CircularProgressBarStates
 * To show the specific status of the process, a `status` property may be used.
 *
 * @overview-example CircularProgressBarTheming
 * Styling of CircularProgressBar is possible with [configuring a custom theme](guides/branding).
