id #	Type `undefined` \| `string` Inherited from `IEntitySettings` A custom string ID for the element. If set, element can be looked up via `am5.registry.entitiesById`. Will raise error if an element with the same ID already exists.
legend #	Type `Legend` If set, plugin will try to manipulate the items in legend, such as adding group slice, hiding items for small slices, etc.
