Does Visustin flow chart generator work well with structured programming?

I am a programmer and at times I would like to generate flow charts for my codes to use during presentations. I have been told about Visustin flow chart generator but I have not been able to acquire one. Since I am still new in programming, I use structural programming as opposed to object oriented. Does Visustin flow chart generator work well with structured programming? How can I acquire this application?
