The simplest of plots is a scatter plot which displays a two dimensional plot of points. The dimensions are the and axes. The observations from the dataset, which are the rows in the dataset, are plotted, scattering the points over the plot.

Using the template variable ds the dataset is piped (%>%) into ggplot2::ggplot(). The aesthetics ggplot2::aes() are set up with min_temp as the axis and max_temp as the axis. To add the points (observations) to the plot we employ ggplot2::geom_point().
