--------------------------------

    Attachment: CRUNCH-105.patch

> It could be very useful to have the ability to create Graphviz[1] dot files[2] based on the outcome of the planner. This could facilitate visualizing the full graph of DoFns as well as jobs and mappers and reducers in a Crunch pipeline.
