Identify each row in the graph with a name

One helpful improvement would be to be able to identify each row in the graph with a name, instead of just “map” you’d have “map (times2)”. Then it's easier to know where the duplication is really coming from and add ".share()" there (as per your medium article examples).

Start by locating the graph row rendering entry point and trace how row labels such as “map” are produced. Update the displayed label to include a useful name, such as “map (times2),” and verify that duplicated operations can be distinguished and associated with the intended .share() location.
