What is the primary purpose of features found in the 'Charts' group of menu items?

The primary purpose of features found in the 'Charts' group of menu items is to visualize data through graphical representations. Charts are essential tools that allow users to transform numerical and categorical data into visual formats such as bar graphs, line charts, pie charts, and more. These visual representations make it easier to understand trends, comparisons, and relationships in data at a glance, as they condense complex information into a more digestible format.

By utilizing charts, users can effectively communicate insights and make data-driven decisions, as visuals can often reveal patterns that might not be immediately apparent from raw data alone. The ability to present data visually is a cornerstone of effective data analysis and reporting within spreadsheet applications.
