Well, there is a Java api exposed by VisualVM - the OQL engine utilizes it. But in order to use it you would need to write your own VisualVM plugin.
I would say that for and ad-hoc analysis the javascript scripting would be much more useful - no need to build/install a new plugin and you can save your analysis definition for later use inside VisualVM.
