Bar graphs display categorical data using rectangular bars of lengths proportional to the values. To interpret a bar graph, identify each category along one axis (usually the x-axis) and the data values along the other (y-axis). For instance, if you chart monthly sales, each bar’s height depicts the sales figure for that month. Bar graphs excel at comparing quantities across groups—like poll results or inventory counts. Plotting them involves labeling axes, scaling units consistently, and ensuring clarity in color or spacing. Bar graphs are a staple of data visualization across business, science, and academic disciplines.
