Help with an usual graph

I am trying to complete a project, and the instructions I was given was to
find/create a "graph" that, as on Blue Peter charity money monitors, looks
like a thermometer gauge and inceases as the amount of money recieved
increases. I don't have any figures yet, i am just wondering if there is a
graph available to do this.
Thanks

LOOK ON PELTIERTECH.COM, he does one there.
