Some other verticals where visual programming is effective: Education, such as the excellent Microsoft MakeCode[0] that lets the user switch between visual blocks and written Typescript. Synthesizers, such as Reaktor[1], that are programmed visually and with code blocks. And scientific instruments, which can be programmed visually with LabView[2].
