Typically, you will need to adopt an approach where you constrain visible marks to a 'window' and add elements to handle 'scrolling' that calculate what to show based on 'progress'. This may take the physical appearance of a scrollbar, but it is a bit more sophisticated. This is the same approach that the core visuals use for 'scrolling' when in categorical axis mode.

You may also need to bind key/mouse events to further simulate scrollbar behavior in the visual. A good example of how to approach this is using Andrzej Leszkiewicz's Table Scrollbar example in the Vega Examples gallery to study the technique.
