 <h2>Examples</h2>
 <p>
 This example specifies 19 separate data points in <b>two tracks</b> (the first is <code>name="variableStep"</code>
 and the second is <code>name="fixedStep"</code> where <code>priority=</code> orders them) in the region 
 chr19:49,304,200-49,310,700. To view this example as a custom track in the Genome Browser, copy the 
 <a href="examples/wiggleExample.txt">text</a> and paste it into the &quot;Add Custom Tracks&quot; 
 text box.</p>
