JavaFX library suggestions needed

Boosts welcome of course.

I'm looking for a library that implements manual layout of components. Imagine something like powerpoint if you like, where you can select objects on a canvas, drag them around and resize them.

I'm building a tool that allows you to create reports that show the results of computations in the KAP editor. I would really like to be able to leverage something that exists than have to implement it myself from scratch.

Is there such a library?
