[1.1. What is Visual Programming Section]
there is an example file called "Visual Programming - Circle Through Point" that accompanies the explanation about the distinction between visual and textual programs. As the name of the file implies it should be a simple code as illustrated in the Primer. But the code that it contains is a bit more complex. It seems the file as been given the wrong title and then misplaced as a result. Don't get me wrong, it's an excellent example about the usage of an attractor point, but I think it can be confusing for newcomers expecting code that simply creates a circle.
