This is a dynamic/interactive java-based TreeView chart.

The main/neatest feature is that you can click/drag on it 
with the left-mouse-button and rotate the tree around
(the bigger/deeper the tree, the more dramatic and
impressive this effect)

There is no "proc" for the treeview, so one of our experts
in the sas/intrnet group wrote a macro (ds2tree) to take 
your sas data and write the correct html to feed your data
into the java treeview chart.

Since there is no proc, many of your usual sas/graph 
tricks aren't available here.  It's a neat/flashy/interactive
way to view your data, and people seem to like it - take it 
at face value, and don't dwell too much on the things you
"can't" do to customize it ;)
