wp8 does not output customized justGage

[Waldo_Y_]

I've been going by the standard documents with xdk and this one is special in its case. I got help and was able to parse data from icecast server and display the data on the justGage. The problem is that the gauge graphics don't show in wp8. I've been using the standard:

<script>
  var g = new JustGage({
    id: "gauge",
    value: 67,
    min: 0,
    max: 100,
    title: "Visitors"
  });
</script>

<div id="gauge" class="200x160px"></div>

and I don't get the graphic shown on the display. Am I doing something wrong or is wp8 OS being picky about having exposed div tags? I also encased it using the Designer tab hoping that the css styling and all will protect the div tags from being exposed to the picky standards of wp8. Then again I'm not sure what's going on? Can anyone shed some light on this?
