  <pre><code>var data = [
          { "latitude": 59.441193, "longitude": 24.729494 },
          { "latitude": 59.432365, "longitude": 24.742992 },
          { "latitude": 59.431602, "longitude": 24.757563 },
          { "latitude": 59.437843, "longitude": 24.765759 },
          { "latitude": 59.439644, "longitude": 24.779041 },
          { "latitude": 59.434776, "longitude": 24.756681 }
      ];
  </code></pre>
