Before adding a chart to a worksheet, what must be ensured regarding the worksheet?

The correct answer is that the worksheet must meet the data requirements for the chart type. This is crucial because different types of charts require specific kinds of data to accurately represent the information you want to visualize. For example, some charts may require numerical data, while others may need categorical data. Ensuring that the data is organized and formatted correctly according to the requirements of the chart type will enable the chart to be generated successfully and convey the intended insights.

If the worksheet fails to meet these data requirements, the chart might not render properly, or it may present misleading information. This consideration is fundamental to creating effective visualizations that enhance understanding and analysis of the data.
