A level 1 diagram would represent a single process contained within a level 0 diagram, and as such, if we were representing process 2 from the level 0 diagram we would ...
Activity diagrams[1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency.
