I agree that we haven’t gained much yet from looking at large graphs. Usually we can reduce any problem of interest to something small. Still, Graphviz produces very ugly results even for small graphs, whereas this is where iongraph shines.

To be clear, what I think makes the latter graph more readable is particularly that the wires are easier to follow. Yes, it’s subjective, but backed up by my own personal experience. Long term I think we can add more interactive features to help us in such cases, e.g. search and dimming irrelevant wires.
