A dot plot is a type of graph in which dots are used to mark the coordinates of categories and their respective values.
Like a bar graph, a dot plot chart has one category axis and one value axis. One of the axes displays the elements/groups of your comparison, the other shows the range of values of your variable. Dots of subsets are assigned with different colors, making them easily distinguishable.
Dot plots are used to visualize the distribution of data points in time series or to compare a data set (with one or more categories) over a single variable, e.g., the revenues and profits from different product lines.

Pro tip: Dot plots enable a clean and easy-to-read visualization of your data. Sometimes, they are a helpful alternative to a cluttered bar chart, also replacing a grouped bar chart. Readers don’t need to compare the length of bars, but only the position of the dot along the value axis. Furthermore, for a dot plot chart, the “start-at-zero” rule for the value axis is not a must.
