I have a hard time reading this graph:<p><a href="http:&#x2F;&#x2F;lh3.googleusercontent.com&#x2F;Dqp5VJzn4SRzlKiWcVdavOWhYIuLGpzrnWTtVTq9FXZlxghcAizk-J8qSa1bls9jFtsKoXO8FiFtMqZplcYh9VT_ZL22=s0" rel="nofollow">http:&#x2F;&#x2F;lh3.googleusercontent.com&#x2F;Dqp5VJzn4SRzlKiWcVdavOWhYIu...</a><p>I can see that on either side of the graduated tiles, the diagonally adjacent plots are mirrors of one another.<p>But the x&#x2F;y dimensions on the quasi-random plots seem so distorted, that information is destroyed. The fact that none of the points are color-coded in any of those tiles, means I can&#x27;t intuitively draw conclusions by noting corresponding dots across second and third tier composites.<p><pre><code>  each time we pick a point, we should pick it 
  as far away as possible from every other point 
  across all dimensions
</code></pre>
I don&#x27;t understand how you can assign a plot like that, and still constrain the mass (M0) and initial helium (Y0) points to the graduated markings on their respective tiles, and come up with a diamond-shaped quasi-random pattern, which still communicates the accurate mass&#x2F;helium relationship for each dot?<p>Why is the upper right corner in those two M0&#x2F;Y0 composites sparse, but there are still diamond grid clusters across the rest of those particular tiles?
