Understand the question is asking about a graphical tool that shows changes in sales volume of a product over time.
Recall that a time-series graph is specifically designed to display data points sequentially over time, making it ideal for showing trends or changes in sales volume.
Recognize that a production possibilities frontier (PPF) illustrates trade-offs between two goods, not changes over time.
Know that a supply curve shows the relationship between price and quantity supplied at a given time, not over a period.
Know that a demand curve shows the relationship between price and quantity demanded at a given time, not over a period.
