Watch for
A circle in the crowded middle swelling as it absorbs, versus a lone new circle popping up out in the tail.
More about this scenario
You'll learn

How it runs
Each add first locates the closest centroid, then checks its size cap; a middle centroid with room absorbs the value while a full one forces a fresh centroid.
