Remarks

Annotations can either be instantiated for an Element or added to the Chart.Annotation collection. When attached to an element, the annotation will follow the element's position (unless specified) and have a spike indicating which element it's referring to.

When an annotation does not have a size or any text specified and it's Box.Background has an image, the size is will become that of the background's image.
