Hierarchical Clustering i.e, an unsupervised machine learning algorithm is used to group the unlabeled datasets into a single group, named, a cluster. Sometimes, it is also known as Hierarchical cluster analysis (HCA).

In this algorithm, we try to create the hierarchy of clusters in the form of a tree, and this tree-shaped structure is known as the Dendrogram.
