I saw this combination of control and data flow graph before a while ago in some paper and while it made sense there (was a very small part of what they described as a whole) it seemed rather trivial / straightforward as a concept. I also heard people reference sea of nodes elsewhere before but I couldn't really get what made it special or a "sea if nodes". Only now I learn that that's basically all it is: data flow and control flow per node/element/instruction combined. I guess without also going into what it actually enables it's a bit underwhelming.
