Node strategy for managing many data points

Earlier with the older JavaFX there were issues where rendering many nodes could really slow the scenegraph down. Is there now some strategy for how to let the scenegraph efficiently render only the nodes for data that actually intersects the visible screen?

In the scenario I'm thinking of nodes decorate data and are more of a temporary thing, so they need to be reusable or else created and disposed of quickly when visualizing the data points.

    [url http://en.wikipedia.org/wiki/Hidden_surface_determination]A variety of strategies have been in existence for a while now, JavaFX just hasn't gotten all of them implemented yet. It looks like JavaFX already uses dirty rectangles. I don't know if or how much culling has been implemented, but I'm sure it will be there sooner or later.
