Writing a variable graph is one of the graphical tools to simplify logic and design. There is no perfect way to write the graph on the variable graph. According to the method proposed in this article, we can get a simpler result. One of the keys to writing a variable graph is to quickly build this graph. Several of the building methods presented in this article are simple and clear.
