title: Using Perl, how can I create charts using values in a CSV file?
body: <p>I am new to this and need a clue on how to do this task. I have a csv file with following sample data:</p>
  
  <pre><code>site,type,2009-01-01,2009-01-02,....
  X,A,12,10,...
  X,B,10,23,...
  Y,A,20,33,...
  Y,B,3,12,...
  
  and so on....
  </code></pre>
  
  <p>I want to create a perl script to read data from the csv file (as per the given user input) and create XY(scatter) charts. Let's say that I want to create a chart for date 2009-01-01 and type B. The user should input something like "2009-01-01 B", and the chart should be created with the values from CSV file.</p>
  
  <p>Can anyone please suggest me some code to start with?</p>
