title: Plot multiple variables on scatter plot
body: <p>I have created a data set that looks like:</p>
  
  <pre><code>&gt; Data
     ZIP.Code Graduation.Rate  Residences  Tax_Payers   Businesses   Pot_Holes
  1     60605      0.00876233 -0.43780716 -0.69756117 -0.705236816 -0.44078331
  2     60607     -0.93779113 -0.62411552  0.45619155  0.429939383 -0.82886125
  3     60608     -0.35352395  0.77774127  0.83458530  0.694500368  0.28789804
  ...
  </code></pre>
  
  <p>The values of each of these features has been scaled in <code>[-1,1]</code> range.
  I wish to have a scatter plot such that the x-axis has the labels of the <code>ZIP_Code</code> and the y-axis has 4 markers for each of the scaled values. How can I do this in R?</p>
