I've been using rerun for a while to visualize the content of inference pipelines, it's nothing short of amazing! I really wanted live views of my gstreamer pipelines, so I've started to write a tool with egui [0]. Looks like rerun's GraphView doesn't support subgraphs and horizontal layouts yet, but I'm sure I'll soon be able to just have a gstreamer tracer that pushes reruns logs. That's better than having to find…
It would be super cool to have layered graph drawing in (Sugiyama-style) in Rerun too. The tricky–but super interesting–challenge that we face is that our layout implementations need to be consistent across timestamps if the underlying structure of the graph changes, which is why we initially chose a force-based layout approach. There, the time-varying aspect is handled naturally by the simulation.
The very interactive nature of Rerun also poses more restrictions on the implementation of our algorithms: re-layouts ideally need to be fast, to produce visualizations quickly, especially when scrubbing the timeline.
I still hope we can rid you of some of the todos ;).
