In informal logic and philosophy, an argument map or argument diagram is a visual representation of the structure of an argument - wikipedia 
Take a look
An argument map typically includes the key components of the argument, traditionally called the ''Logical consequence'' and the ''premises'', also called ''Main contention'' and ''Reason (argument)s''.

# Description
An argument map typically includes the key components of the argument, traditionally called the conclusion and the premises, also called contention and reasons - wikipedia
Argument maps can also show one or more of the following: - Co-premise - Objection - Counterargument - Rebuttal - Lemma
There are different styles of argument map but they are often functionally equivalent and represent an argument's individual claims and the relationships between them.

Argument maps are commonly used in the context of teaching and applying critical thinking. The purpose of mapping is to uncover the logical structure of arguments, identify unstated assumptions, evaluate the support an argument offers for a conclusion, and aid understanding of debates. Argument maps are often designed to support deliberation of issues, ideas and arguments in wicked problems.
An argument map is not to be confused with a concept map or a mind map, two other kinds of Graph (discrete mathematics) which have different constraints on nodes and links.

According to Doug Walton and colleagues, an argument map has two basic components: "One component is a set of circled numbers arrayed as points. Each number represents a proposition (premise or conclusion) in the argument being diagrammed.
The other component is a set of lines or arrows joining the points. Each line (arrow) represents an inference. The whole network of points and lines represents a kind of overview of the reasoning in the given argument..." With the introduction of software for producing argument maps, it has become common for argument maps to consist of boxes containing the actual propositions rather than numbers referencing those propositions.
