A pie chart is the best choice for portraying the distribution of the value categories of a nominal level variable. It represents each category as a slice in the pie, and the size of each slice is proportional to the frequency or percentage of that category in the data. Other graphs like histograms and stem and leaf plots are used for continuous or numerical variables, and may not be appropriate for nominal level variables.
