An Animation contains the data that defines how a [Skeleton](https://api.playcanvas.com/engine/classes/Skeleton.md) animates over time. The
Animation contains an array of [AnimationNode](https://api.playcanvas.com/engine/classes/AnimationNode.md)s, where each AnimationNode targets a
specific [GraphNode](https://api.playcanvas.com/engine/classes/GraphNode.md) referenced by a [Skeleton](https://api.playcanvas.com/engine/classes/Skeleton.md).

An Animation can be played back by an [AnimationComponent](https://api.playcanvas.com/engine/classes/AnimationComponent.md).
