Is there a graph system that can be used e.g. in legal and other contexts for drawing conclusions?
With a "graph system" (sorry if it is not the right word) I am referring to a set of agreed symbols. With "drawing conclusions" I mean using these graphs to help come to conclusion about various subjects.
I gave the legal context as an example as it is one where an argument would start from a premise and then use additional data to build up to some conclusion. So it should be possible to use the graphs to show the process from premise and data to conclusion.
This would be for a website (that I have been planning to build) where a community of users can draw conclusions together.
