I've been working on a concept map for joins. I'm similarly not completely satisfied, but I thought I would share for feedback and collaboration.
In working on this, I've realized that one conceptual challenge is that the while all joins involve two tables, the verb of the operation is different for mutating and filtering joins — mutating joins combine while filtering joins filter.
I liked and I tried to retain the table structure from the current concept map, but I tried to incorporate the row-matching that occurs when joining tables. Although now comparing again to the current version, I've lost the filling with NA concept.
Feedback welcome and I'll be happy to iterate on this or open a PR to submit more formally.
