Hierarchical clustering of networks

Hierarchical clustering of networks is a way of organizing networks or groups of things (like people, animals, or computers) into different categories or "groups". It works by looking for patterns in the connections between the things. For example, if you have a network of people, a hierarchical clustering algorithm would look at who's friends with whom and group them together accordingly. This can be useful for categorizing social networks, detecting relationships between different parts of a computer system, and many other things.
