Here is a grapher that I made! Enter a NUMBER from 1 to 10 for the price, and for the supply or demand enter a number that is a multiple of 10, ranging from 10 to 100 (you can use both numbers). To enter a supply or demand, click on the data button. If you want to delete something that you added, click on the trash can button. It will ask for the index (in the lists) of that item that you want to delete. Click on the "Sketch" button to draw your thing.
