Visual programming does not work well mostly due to a physical problem: typing characters into a computer is much faster and flexible at generating imperative code than using a mouse. There are declarative domains, such as simple UI building, where that is less true, but even then, when you kick out to the event handler, text is much faster. IntelliJ has done more for visual programming, by integrating visual/wizard aspects seamlessly into a text-dominant environment, than almost all the visual programming advocates of the last fifty years. Visual environments do demo well, and sometimes convince businessmen that they won't need to pay those annoying and expensive programmers so much money. Hence its enduring appeal to the business world.
