In R, you build a graph step by step. You start with a simple graph, and then add features to it with additional commands. You can even combine multiple plots and other graphs into a single graph. Besides viewing the graph interactively, you can save it to a file. There are many functions for drawing graphs. Let's start with the most basic one, the plot() function.
Note that, if you removed the TM dataset from memory or didn't save the workspace when you exited the last session, you need to re-read the dataset. Here is the code that uses it to draw a graph for the Education variable of the TM dataset, which is also added to the search path to simplify further addressing to the variables:
TM = read.table("C:\\SQL2017DevGuide\\Chapter13_TM.csv", ...
