When comparing data across multiple categories it is crucial for the reader to understand the graph first. A good graph will label their axis’ along with the numerical values of their data. When analyzing the graphs, the reader can use the similarities between the graphs and the data to compare them. Through this comparison of data, a deeper understanding of the graphs can be reached. Visualizing the data makes comparing data especially easy, as the reader can quickly go from graph to graph reading the data.
