cluster

A cluster is a group of similar things or items that are located close to each other or share common characteristics. In data, it refers to a collection of data points with common features, identified through analysis, which helps in categorizing or understanding patterns. For example, a cluster of stars in the sky appears close together, or in business, customer clusters can reveal groups with similar buying habits. Clustering helps organize and make sense of complex information by grouping similar elements, making it easier to analyze and draw insights.
