This is not the most effective graphing type. A line graph is more effective because they are commonly used to express a change over time. In addition, line graphs are also used to compare numerical factors that would have an effect on each other. This is true for number of suits and time. Furthermore, bar graphs are commonly used to compare a quantitative (numerical) and qualitative (non-numerical) factor that do not affect each other. For example, store number and number of suits sold would be a bar graph.
