title: Can I use rrdtool with Perl to make graphs from CSV files?
body: <p>Below is the sample data format in my CSV file.</p>
  
  <pre><code>date,&lt;options&gt;
  YYYY-MM-DD,&lt;values&gt;
  </code></pre>
  
  <p>Every next morning this CSV file has been updated with next date values. Can I use rrdtool to create graphs, and if so how?</p>
