A graph is a chain of reasoning, not a picture to copy
Students often remember the final diagram but lose the mechanism that produced it. Was there a change in price, which means movement along a curve, or did a non-price condition change, which may shift the curve? Which market or time horizon does the model describe? A small wording difference can alter the entire analysis. Online economics help is most useful when it slows down that chain and asks you to defend every move.
