First, set up the plots and store them, but don’t render them yet. Welcome to MapCustomizer. A simple graph is a graph having no loops or multiple edges. The fact that each input value has exactly one output value means graphs of functions have certain characteristics. The details of these plots aren't important; all you need to do is store the plot objects in variables. The primary data set used is from the student survey of this course, but some plots are shown that use textbook data sets. The R code to generate this type of plot would look like this:.
