MoreCooler.com: It's more cooler with the thing

Does anybody know a good way to display line graphs on a web page? They do not have to be dynamic, but I would need either around 40 small graphs or 1 big graph with 40 lines. Any suggestions?

Look at the bottom right square. Does that bring back memories or what? =)
