I'm not sure if it's really that popular but Visual Programming gives the ability for designers to quickly implement their ideas without having to ask and waiting for a programmer to implement them via code.
For example, in the case of Unreal Engine, gameplay programmers build the basic blocks via C++, and game designers can access them via Blueprint (Unreal Engine's visual programming tool).
