Is there any visual programming language well-suited to implementing complex data structures like red-black trees? What about a recursive descent parser? File system? I have not used visual languages extensively, but it seems like they are better suited to simple control flows with flat data structures and limited state mutation. This would explain their success for graphics shaders, audio, industrial control, etc.
