Klyra
Find the groups that were always there.
What it is
Klyra is an animated k-means clustering tool that discovers natural groupings in a set of points and runs the algorithm to convergence before your eyes. The signature technique is Lloyd's algorithm with k-means++ seeding, inertia tracking, and best-of-N restarts, anchored by tests on the monotonic-inertia guarantee and reliable recovery of well-separated blobs. It is a from-scratch, dependency-light build you can download and run locally.
Lloyd's algorithm with k-means++ seeding, inertia, and best-of-N restarts, animated to convergence. 13 tests anchored on the monotonic-inertia guarantee and >95% recovery of well-separated blobs.
