What is the primary purpose of using a graph in data representation?

Using a graph to represent data primarily serves to simplify complex information. Graphs are visual tools that condense large amounts of data into an easily digestible format, allowing viewers to quickly grasp trends, patterns, and relationships that may not be immediately evident in raw data. By transforming numbers into visual elements, graphs enhance understanding and facilitate effective communication of information.

This simplification is crucial in educational and professional settings, where stakeholders need to make informed decisions based on data analysis. Graphs can illustrate comparisons, show distributions, and unveil relationships between variables in a straightforward manner, promoting clarity over confusion.
