As discussed in Assessing Shape of a Variable’s Distribution, assessing the distribution of variables is often desirable. In that section, we

or not - in this case you can visually check the graph for differences between the
perfect mathematical model of the black normality line and the actual data. Figure 7.11 Example of tenure data histogram with comparison to normality is another example of comparing data to a perfect normal line in a histogram.
