The FoC environments create new classes of bugs. My last livestream got screwed up by an errant dataflow dependency which was impossible to find in the heat of the moment so I made a tool to help me solve this class of bug faster. (kudos to the observable plot library too which helped me make the visuals much faster too). You can play with the dataflow debugger in your browser yourself here

This tools (hopefully) helps communicate the idea each cell is really a stream of values
