Other ggplot2 layers

A line plot is one way to display this data. You could also choose to display it as a scatter plot, with each year represented as a single point. This requires changing the layer (i.e. geom_line() to geom_point()).

You can also add additional layers to your graph, such as a smoothing curve with geom_smooth().
