A dot plot can be used in the same way, as shown in Figure 4-18. Again, the data and axes are the same and the visual cue is different.

Like bar charts, dots put focus on each value, and trends can be harder to see. Although in this example, there are enough data points, so you don’t need to mentally fill in the gaps. If the data were more sparse, such as in Figure 4-19, changes are less obvious.

When you connect the sparse dots with a line, as shown in Figure 4-20, the focus of the plot shifts again.
