For instance, here's a simple graph (I can't use drawings in these columns, so I write down the graph's arcs): A -> B A -> C B -> C B -> D C -> D D -> C E -> F F -> C. This graph has six nodes (A-F) and eight arcs. It can be represented by the following Python data structure:3D graphs in python. 3-D graphs in python can be useful in certain circumstances. For example, when you are trying to show the correlation of more than two variables to one another.
