Computer-Implemented System And Method For Building Cluster Spine Groups

A computer-implemented system and method for building spine groups is provided. Cluster spines, each having two or more clusters, are displayed. One or more candidate anchor clusters are identified for each of the cluster spines. Additional cluster spines are placed into the display by selecting one of the additional cluster spines and identifying one of the displayed cluster spines that is most similar to the selected additional cluster spine. A spine group is formed by grafting one of the clusters on the additional cluster spine to one of the candidate anchor clusters of the most similar cluster spine. An angle of the selected additional cluster spine is changed when the most similar cluster spine and the selected additional cluster spine exceed a maximum line segment.
