That scaling will work.  thanks!  But I had decided that BubbleChart[]
wasn't doing that much for me, so I generated a Table of my own Disks using
a fixed scaling across different tables.  Then using Graphics to show the
disks gave me a lot of control.

My bad (at least partially) on Ticks and some other things now working.  I
didn't realize that BubbleChart was giving me a frame instead of axes and
that I needed to turn Frame off or use FrameTicks.  in any case, everything
works now.

thanks!
