Basically (as I see it) the number of levels of click-through (drill down) are unlimited. Each level of drill down would be another set of SAS graphs that you've created, and each set of graphs could have its own drill down. With SAS/Graph, there's nothing really built-in/automated that does it -- you just have to go through and create each level.
The "tricky" part is that you have to know the urls (relative, or absolute) to code in as your drill down at each level.
If you want the SAS/Graph graphs (and drill-downs) in real-time, then you'll have to run the graphs using SAS/Intrnet (or Stored Processes).
Stored Processes will be the direction I am heading to. Thank you! Robert.
