For students across the sciences to avail themselves of modern data streams, they must first know how to wrangle data:  how to reshape ill-organised, tabular data into another format programmatically.  Although data wrangling as a programming domain presents distinctive challenges, such as the need for on-the-fly syntax lookup and code example integration, it also presents opportunities.  One such opportunity is how tabular data structures are easily visualised.  To exploit the inherent visualisability of data wrangling, my dissertation evaluates three types of graphics that could be employed as scaffolding for novices:  subgoal graphics, thumbnail  graphics,  and  parameter  graphics. The presentation will give a sweeping tour of the studies I undertook, and what the evaluations imply for data wrangling instruction.
