Size and symbol

To change the default size and shape of points on a scatterplot or boxplot, we pass the marker argument a list with the size and symbol arguments. As you have seen, changing the plotting symbol can make charts easier to read by addressing issues such as overplotting. Decreasing the size of points can also help overcome minor overplotting issues—just don't make the points hard to see!
