void Layout() override
Perform the layout.

static vtkCosmicTreeLayoutStrategy * New()
RadiusMode
How are node sizes specified?
@ NONE
No node sizes specified... unit radius is assumed.
@ LEAVES
Only leaf node sizes specified... parents are calculated during layout.

Create an array to hold scale factors, named appropriately (depends on NodeSizeArrayName) and initial...
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
