A scatter plot is simply a set of points plotted on axes. You can draw a scatter plot with the scatterplot or nuage_points command.

You can call scatterplot with a matrix with two columns (essentially, a list of points) or a list of x-coordinates followed by a list of y-coordinates. If you enter

you will get
