There are other advantages to this method: easily showing which wires are active while debugging, giving new programmers an intuitive sense of what's happening in control structures like for loops, using color, symbols and line weights to intuitively convey things about data/object types, giving users a complete list of potential methods and parameters without having to look for it, being able to use more complex code shapes to navigate complex classes, people can learn the basics of coding logic without needing to memorize syntax simultaneously... There are obviously tons of shortcomings to visual code, but I do think a lot of the guff they get is unwarranted.
