What are charts used for in spreadsheets?

Charts in spreadsheets serve the purpose of visually representing data. This visual representation makes it much easier to interpret complex information quickly by highlighting trends, patterns, and relationships within the data. For example, a line chart might show how sales figures have increased over time, while a pie chart could depict the proportion of different sales categories. By transforming raw numbers into visuals, charts enhance understanding and facilitate communication of data insights, allowing users to make informed decisions based on what they see.

Other functions listed, such as formatting data in tables, storing data securely, or performing calculations, are important features of spreadsheets, but they do not provide the same level of insight into trends and comparisons as charts do. The primary value of charts lies in their ability to make data more accessible and interpretable through visualization.
