I had to make these as part of an introductory programming class in college, using this specific software. I'm not sure if it's a shortcoming of the software or the overall idea of an NS chart/diagram, but boy, these suck. We were using Java in the class I had to write them for, and a lot of ideas weren't smoothly represented with these charts. They were a pain in the ass more than anything, and I have no idea why I would painstakingly rewrite the program in an overly verbose chart when I could just be writing the program and properly commenting it.
