+the Vega JavaScript library. It's often helpful to inspect transformed data
+results in the process of building a chart. One approach is to display the
+transformed data results in a table composed of :ref:`Text<user-guide-text-marks>`
+marks as in the :ref:`gallery_scatter_linked_table` gallery example.
+
+While this approach works, it's somewhat cumbersome, and still does not make it
+possible to access the transformed data from Python. To make transformed data
