Notebook to study Betweenness Centrality of a graph

[PurviChaurasia]

I am extremely interested in studying the algorithm behind calculating the betweenness centrality in graphs. It's widely used and a notebook explaining it would be beneficial to any person who aims to use the function.
The current algorithm is referred from -
