Which option describes a chart in a spreadsheet?

The correct answer describes a chart in a spreadsheet as a representation of data in a more visual format. Charts are essential tools in spreadsheets because they transform numerical data into graphical formats, such as bar graphs, line charts, and pie charts. This visualization helps users quickly understand trends, patterns, and comparisons within the data, making it easier to grasp complex information at a glance.

Visual representations facilitate better communication of the data's significance, especially when presenting findings to others. By converting numbers into visual elements, it enhances the audience's ability to interpret the information effectively.

Other options do not accurately depict a chart. For example, using a formula pertains to calculations, while formatting text concerns how the text looks (font type, size, color), and sorting data refers to arranging it in a particular order. None of these concepts encapsulate the function of a chart in a spreadsheet environment.
