As an alternative to plotting the points we could join the dots and plot a line. One reason for doing so might be to attempt to observe more clearly any relationship between the two dimensions (i.e., the two variables we are plotting). Add a ggplot2::geom_line() to the canvas we can draw a line from left to right the follows the points exactly. The result is a rather jugged line and it is debatable whether it has added any further insight into our understanding of the data.
