Updating aesthetic labels

In this exercise, you'll modify some aesthetics to make a bar plot of the number of cylinders for cars with different types of transmission.

You'll also make use of some functions for improving the appearance of the plot.

  • labs() to set the x- and y-axis labels. It takes strings for each argument.
  • scale_color_manual() defines properties of the color scale (i.e. axis). The first argument sets the legend title. values is a named vector of colors to use.
