Layers are collections of items, such as shapes, lines, or groups. Layers cannot contain other layers. They are similar to Groups but are more versatile. Layers are used to organize and manage the visual hierarchy of elements within a diagram. You can assign shapes, lines, and groups to different layers and then manipulate the visibility and order of those layers.
