To determine what is during the file style describe. (This command may be abbreviated to just one letter, but I want desc.)

To see how lifetime expectancy differs with GNP for every capita we will draw a scatter plot using the graph command, that has a myriad of subcommands and options, some of which we explain in Area 3.
