Dot plots can be made easily in R (r-project.org), if you use R. But R has a steep learning curve if you have grown up using Excel. One of the first books about information design written for statisticians. Although there are plenty of online tools out there for making dot plots for tests, quizzes, or lecture slides, I was generally put off by what they required of me. We can further increase the scale to avoid overlapping of data points. Here, we’ll use the R built-in mtcars data set.
