Which of the following best describes an Excel chart?

An Excel chart is best described as a graphical representation of data. This means that charts help visualize numerical information, allowing users to see patterns, trends, and comparisons in a manner that is often more intuitive than looking at raw data in rows and columns. By transforming data into graphical formats such as bar charts, pie charts, or line graphs, users can quickly interpret the information and communicate findings effectively.

In contrast, the other options do not accurately capture the essence of what a chart represents in Excel. A text document refers to plain text files and not the visual data representation that charts provide. A type of formula pertains to calculations made within Excel cells, while a list of functions consists of predefined operations within Excel, such as SUM or AVERAGE, which are used in formulas. None of these alternatives align with the primary purpose of a chart in the context of data representation.
