Hi Daniel, Thanks a lot for the reply. I installed the latest Pig and read through the book of "programming in pig". I manged to use "-dot -out filename" to produce three graphs in dot file format.
Based on the existing dot file, my next question is what is the requirement regarding a better visualizer? Are we going to generate a picture (e.g., .png) for different plans (logical plan, physical plan, map reduce plan), or provide a web interface to visualize these graphs of plans?
