Find an example online of a graph used in real life. Please provide the link to the web page by using the link button in the editor. Describe at least one mathematical feature of the graph (e.g. shape, slope, coordinates, axes, quadrants, etc.) and how the feature/graph can help us to analyze the real-life situation.
We give the example of the Dow Jones Industrial Average (DJIA) as a graph widely applicable to real life and explain some of its key features.
