1. A method of providing an interactive representation of a data set of sequential data, the method comprising: receiving, by a computer system, the data set comprising a plurality of ordered data sequences, wherein each data sequence corresponds to an ordered sequence of related data points; clustering, by the computer system, the plurality of data sequences into a hierarchical set of clusters of the sequential data; generating, by the computer system, a dendrogram structure based on the clustered sequential data, the dendrogram structure representing a hierarchy of the clustered sequential data; presenting, by the computer system, the dendrogram structure within a page of a user interface, wherein the dendrogram structure comprises a graphical representation of an aggregate ordered sequence of the plurality of ordered data sequences, and wherein the user interface page includes a detail view illustrating detailed information for each cluster of the hierarchical set of clusters of the dendrogram structure, and wherein presenting the dendrogram structure within the page of the user interface further comprises, for the each cluster of the hierarchical set of clusters of the dendrogram structure: (a) generating a graphical indication of a shaded circle corresponding to a degree to which involved pairs of the clusters match, wherein the degree to which the involved pairs of the clusters match is represented by a level of shading of the shaded circle, and (b) presenting the graphical indication of the shaded circle at a particular location within the dendrogram associated with the involved pairs of the clusters; receiving, by the computer system, user input via a slider control of the user interface page, the user input selecting a depth for the dendrogram structure, wherein the slider control indicates a currently selected depth level of the dendrogram structure, the slider comprising a user repositionable marker to indicate the currently selected depth level of the dendrogram structure; dynamically re-clustering, by the computer system, the plurality of ordered data sequences into a new hierarchical set of clusters of the sequential data, based on the received selection of the depth of the dendrogram structure via manipulation of the slider control; re-generating, by the computer system, the dendrogram structure based on the reclustered sequential data; and updating, by the computer system, the user interface page with the re-generated dendrogram structure, wherein updating the user interface page includes updating the detail view illustrating the detailed information for each cluster of the re-clustered hierarchical set of clusters at the selected level of the dendrogram structure.
