A dendrogram is a hierarchical representation of the arrangement of clusters that we get from an analysis. It looks like a network of connections. The point where the visualization starts are known as the root node. From the root node, the hierarchy starts, the connecting line joining further nodes are branches, and the last nodes are called leaves.

Why do you need it?

We need Dendrogram to visualize an arrangement in such a way that looks pleasant, attractive, and effective to analyze. The height of the branches represents
the order in which clusters get arrange.

What kind of data you can visualize with it?

The Dendrogram is best suited to hierarchical-data. Assume you have data of employees of an organization, then the CEO will be the root node that connects to the manager’s node branches, and further, the employee under each manager will be presented as the last node.
