DendrogramsDendrograms are often used for displaying relationships among clusters. A dendrogram shows the multidimensional distances between objects in a treelike structure. Objects which are closest to each other in the multidimensional data space are connected by a horizontal line, forming a cluster which can be regarded as a "new" object. The new cluster and the remaining original data are again searched for the closest pair, and so on. The distance of the particular pair of objects (or clusters) is reflected in the height of the horizontal line. Dendrograms are heavily dependant upon the measure used to calculate the distances between the objects.
