You probably want to look at the viewbox and width and height
attributes on the SVG element in the SVG specification. Unless you
are trying to do something much more complicated than I think you are
you should be able to get the behaviour you want by setting these
attributes appropriately for the Graph.
The actual problem you are having is that you need to wait until
the 'internal tree' is built before trying to set the rendering
transform.
