Those two are both primarily for real time signals and music right? That is a great domain for wires, transforms, and pipelines.

Have you ever seen them used in a different context?

GNU Radio Companion is its RF/software-defined radio counterpart: https://wiki.gnuradio.org/index.php?title=Your_First_Flowgra...

Sometimes the flowgraph is too complex to be constructed using the visual editor though, for example gnss-sdr uses C++ to generate the GNU Radio flowgraph: https://gnss-sdr.org/docs/control-plane/

No, they are very tailored to that use case. They arent general languages - but they are still probably the best examples of successful visual programming languages.
