Get your boss to spring for another machine thats yours to do what you like with.

If your IT department won't let you play in their sandbox, get your boss, or the people who want the dynamic graphs to help you out.

Tell them 'i'd love to help you out, but i need a machine to run this stuff on. Any old pentium will do.' And you might be surprised what some marketing manager who really wants a pretty graph for his presentation will come up with.

If this is simply impossible, then simply tell the guys who want the graphs that the IT department says they can't have them, and watch the sparks fly as the underclued marketers push the IT department into allowing you full root access to all their servers.

The Sysadmins will give you dark looks from over their full beards, but thats the price of progess.
