All you need to do is do ellipses and have either the X or the Y be driven by the data. One the other hand, I thought I would try to show you something slightly more interesting than that, and what I've done is I've created a dot plot using the Google data file that I used in the last chapter. If you open up the folder for chapter 11, exercise one, what you'll find is a few things in there. First off, you find the actual Processing file itself. That's one that says Ex11_01. That's the file we are looking at right here. You will also find the Table, with a capital T. That is the table class that we will be using to help process the data, and you can see for instance, in the Processing sketch on the left…
