+@code{@@series} which will define a custom transformation and attach attributes
+for user types.  Its design is an attempt to simplify and generalize the
+summary and display of types and data from external packages.  With no extra
+dependencies and minimal code, package authors can describe visualization
+routines that can be used as components in more complex visualizations.")
