+    (description
+     "The Datasaurus Dozen is a set of datasets with the same summary
+statistics.  They retain the same summary statistics despite having radically
+different distributions.  The datasets represent a larger and quirkier object
+lesson that is typically taught via Anscombe's Quartet (available in the
+'datasets' package).  Anscombe's Quartet contains four very different
+distributions with the same summary statistics and as such highlights the value
+of visualisation in understanding data, over and above summary statistics.  As
+well as being an engaging variant on the Quartet, the data is generated in a
+novel way.  The simulated annealing process used to derive datasets from the
+original Datasaurus is detailed in \"Same Stats, Different Graphs: Generating
+Datasets with Varied Appearance and Identical Statistics through Simulated
+Annealing\" @url{doi:10.1145/3025453.3025912}.")
