Easy - everything is dynamic at run-time in VisAD. At run time
you'll link a DataReference to a DisplayImpl via a addReference()
call. Then simply construct a FlatField with whatever size domain
Set you like and pass it to the setData() method of the
DataReferncee.

Every VisAD example builds and sets data sizes at run-time.

Cheers, Bill
