Centrality in Graph Theory
One of the key points of Graph Theory is that it conveys an understanding of how things are interconnected via nodes (points where various paths meet) or edges (the paths connecting the nodes). There are a number of different types of graphs, of which the most well-known are digraphs (directed graphs, whereby A may lead to B, but the reverse may not be true), an undirected graphs (where there is no implied directionality)....
