A graph is a great way to summarize a description of an event or a situation. Using a graph has several benefits. One benefit is that graphing makes the description more visual and, therefore, more engaging. Another benefit is that a graph can capture multiple aspects of a situation in a concise manner, whereas it may take many sentences to describe one aspect of the scenario. A third benefit is that a graph can be used as a tool to analyze trends and uncover patterns.
In this part of the lesson you will learn how to convert descriptions of scenarios into graphs.
