<li><p><strong>3Clusters of 3Clusters</strong>: Points are drawn with 9 different centers, which can be loosely grouped into three groups of three; again uses Clusters() with <cite>sd = 0.05</cite>. The centers are <cite>[0,0], [0,1.5], [1.5,0]</cite>; this set rotated 45 degrees and shifted up by 4; and the first set shifted right 3 and up 4.</p></li>
