dendrogram

A dendrogram is a tree-like diagram that visually represents how different data points or groups are related based on their similarities. Imagine it as a family tree, where each branch connects similar members, and the height of each split indicates how closely related they are—the lower the split, the more alike. Dendrograms are commonly used in data analysis to cluster similar items together, helping us see patterns and groupings within complex information, such as identifying related genes in biology or customer segments in marketing.
