title: SAS: how to create a bubble plot for ordinal variables
body: <p>I would like to make a bubble plot of two ordinal variables plotted against each other, with a loess line plotted trough it in SAS, could somebody help me with this?</p>
  
  <p>More specific: </p>
  
  <p>The two variables contain scores between 0 and 10.
  my data looks pretty much like this:</p>
  
  <pre><code>data dataset;
  Obs var1 var2
  1   0    4
  2   3    2
  3   3    2
  4   2    5
  5   6    9
  6   7    9
  7   1    7
  8   7    9
  </code></pre>
  
  <p>What I'm doing right now is just making a scatterplot and drawing a loess line trough it, but since a scatterplot of this kind of data only gives you a roster-like graph, I would like to make a bubble plot out of it to represent the frequency of each case... (so in my example the bubbles in (3,2) and (7,9) would be a bit bigger than te rest)</p>
  
  <p>Afterwards however I would like to still be able to draw that loess line trough it...</p>
