After discussing the use of flow diagrams in CityLoops, their use is now in full swing and first results can be seen: https://cityloops.metabolismofcities.org/flowdiagrams/ . Check out the FDs of dairy products or fish, for example.
Now that the FD builder is used, we are seeing how complex a material's connections can be, how practical the use of the tool is (or isn't) and how small the diagrams become. For the latter, we can implement a full screen view, as was already discussed with Guus.
But, another issue that was raised, by Carla, is that there is no possibility to create a "one to many" relationship, i.e. one origin to several destinations, at once or in one go, which would be more practical. Instead, the single origin-destination connections have to be build one by one.
Before making a task for this, I wanted to discuss here if (1) this is technically possible and (2) if that makes sense from an editing perspective or table view, because the single connections still have to be displayed in the end. @Paul and Aris, what do you think?
