Programming Languages for Generative design: Visual or Textual?

In this paper we compare visual and textual programming languages for generative design.We argue that, in the past, this comparison has been flawed and that it is now time to reconsider the potential of the textual programming paradigm but using modern programming languages and development environments specifically targeted to the generative design domain.We present VisualScheme as a prime example of such language and we compare it with the most used visual programming language in the generative design field.
