The articulation point which we come across in the real world can be observed in many situations. Basically in the graph theory, An articulation point is also known as a vertex and when it is removed with the linked edges existing, it disconnects the graph.
Articulation points are also known as weaknesses in a connected network where a single point failure in the network would break the chain into two or more components.
