Converting MSDN SPSiteDataQuery Example to use SPGridView

I've read it's "easily" possible to convert the MSDN SPSiteDataQuery example from using GridView to using SPGridView. I've been working on it and can't quite get it to work. If anyone knows how to 'easily' do this, can you please share?

MSDN Example:

THANK YOU!
