Description

I have been tracking down issues in our use of DataFusion for my work project, and I have found myself wanting to print out the state of the logical_plan several times. The existing debug formatting is ok, but it is missing a few key items:

1. schema information (as in when did columns appear / disappear in the plan)
2. A visual representation (graphviz)
