If you define a frame interface for a visualization and reference it, then this construct behaves like a visualization element:
When creating the frame interface on the Frame Configuration tab, you can define which properties will be public. You can create an interface yourself.
You can categorize the properties and structure them hierarchically to provide for a clear overview.
The visualization can be reused as often as you want, which means that they are referenced by means of a frame in a superordinate visualization.
When the frame is selected there, exactly those properties which were defined in the frame interface are displayed in the Properties view. Now when you configure the properties, you will get help as usual from the editors which are provided in the view. The handling is the same.
