    \brief The GraphAnimation type is the base type for all animations for 2D Qt Graphs series.

    GraphAnimation is based on VariantAnimation and provides an interface for interpolation for child animations.
    This type is an abstract type and doesn't have any default implementation for interpolation. Its derived types
    should be used for the respective animations, such as GraphPointAnimation, SplineControlAnimation.

/*!
    \qmlproperty GraphAnimation::AnimationState GraphAnimation::animating

    Holds the animation state. One of \l {GraphAnimation::AnimationState}.
 */

/*!
    \qmlproperty enumeration GraphAnimation::AnimationState

    Animation states.

    \value Playing
        Animation is playing.
    \value Stopped
        Animation is stopped.
