How do you enable the chart title for visibility in PowerPoint?

To enable the chart title for visibility in PowerPoint, clicking the chart elements button and checking the chart title is the correct approach. This button usually appears as a plus sign (+) next to the chart when it is selected. By clicking on this button, you open a menu that allows you to toggle various elements of the chart on or off, including the chart title. This method is user-friendly and provides a quick way to customize the chart by adding or removing elements as needed.

This option stands out because it directly interacts with the chart itself and provides a straightforward method to enhance visibility by ensuring the title is displayed. Other options, while they may mention relevant concepts, don't provide as direct a means to enable the title specifically as the chart elements button does.
