> Impala query plan can be huge and complex.
> It becomes hard to analyze this complex query plan, its execution summary, and the runtime filter interactions from the query profile.
> We need tool to help visualize this query plan from plain text query profile.
> One solution is to write a python script to parse the text profile into a GraphViz DOT format.
> This DOT file can then be parsed into image using dot program or immediately visualize using program such as ZGRViewer.
