  "Description": "Implements a fast and resistant divisive clustering\nalgorithm which identifies a specified number of clusters:\n'lumbermark' iteratively chops off sizeable limbs that are\njoined by protruding segments of a dataset's mutual\nreachability minimum spanning tree (Gagolewski, 2026\n<DOI:10.48550/arXiv.2604.07143>).  The use of a mutual\nreachability distance pulls peripheral points farther away from\neach other. It is a viable alternative to the 'HDBSCAN*'\nalgorithm and can be viewed as a divisive version of Genie. The\nresulting partitions of different granularities are properly\nnested. When combined with the 'deadwood' package, it can act\nas an outlier detector. The 'Python' version of 'lumbermark' is\navailable via 'PyPI'.",
