title: jQuery.ajax is not a function error
body: <p>I'm trying to call the following function in some javascript code. The JS code that's calling it is actually an example from the Javascript InfoVis tutorial. I try to call a server so that I can use the return value to draw a custom graph. The error I get in FireBug is "jQuery.ajax is not a function". </p>
  
  <p>I have an HTML page that loads both the jQuery script and InfoVis tutorial. Is something wrong with the example below?</p>

  <pre><code>jQuery.Ajax({
      type: "POST",
      url: "http://localhost:8000/applications/nvn",
      data: "GetNVN",
      success: function(msg){
      var fdsa;
      fdsa++;
      init(msg);
      }
  });
  </code></pre>
