> From time to time, we want to visualize the plan generated the optimizer as a DAG (Directed Acyclic Graph). This gives us an overview of the plan, and helps us to find problems with the plan quickly.
> A common way to visualize a DAG is to dump it in the {{dot}} format, and then display the DAG through GraphViz. Currently, we already have a utility to dump the Volcano planner in dot format. In this issue, we want to dump a RelNode plan (a RelNode DAG) in the dot format, which will help users to see their plans more clearly.
> The utility should have some options that allow users to specify the visuzalization details, for example:
> 1. the max length of a node description.
> 2. whether RelSubset/HepRelVertex should be displayed.
> 3. Nodes that should be highlighted.
> Could you please give some feedback?
