"Would have been a good activity but we couldn't get the whole graph displayed on the screen/white board"

"Thanks for your feedback Mr Gray. The graph is designed to be as big as possible while still fitting on an 800x600 screen. If you are using Internet Explorer press the F11 key to hide the toolbars. If they don't all disappear you may need to right click and choose autohide."
