This guide provides essential concepts for mastering graphing skills, focusing on two primary types of graphs: bar graphs and line graphs. Bar graphs are used to display data in distinct categories, featuring key elements like titles, labeled and scaled axes, and separated bars. Line graphs, on the other hand, illustrate how one variable responds to another, suitable for continuous data. Both types require proper axes and plotting techniques. Understanding these elements is crucial for effective data representation and analysis.
