There are simple solutions to get the size of the drawing reduced, such as setting the size and 
fontsize attributes. This won't do you any good, because your graph is
fairly dense and, more importantly, it's very bushy, There are 5 nodes on level 1, 28 nodes on level 
2 and 135 nodes on level 3. You can stagger the edge lengths to help
some, but you still have long edges crossing levels, adding to the width. The nodes can be 
compressed within each rank, and then the edges can be redrawn using the
available space, but the resulting layout will probably be ugly. Even if you packed the last level 
as 13 rows of 10 nodes each, and used a small font size, that would still
take a lot of room on a page.

For the record, I have attached a layout using staggered nodes. This was produced using

      dot graph.gv | gvpr -c -f unflatten | dot

where I've also attached the gvpr script unflatten.
