MSTs and time-series data. An example with a time-series data set of three samples (T1, T2, and T3) where the dissimilarity between T1 and T2 is the smallest, but between T2 and T3 is the largest. This phenomenon is depicted well by the MST (left), but not by the dendrogram (right) since T1 and T2 are part of the same sub-tree and could be re-ordered depending on the hierarchical clustering implementation.
