title: Google Charts: Line Chart: Doesn't display in IE and Firefox, but works in chrome
body: <p>I have a simple chart (albeit with a lot of data) that renders fine in chrome but doesn't render in IE or Firefox. Since I don't know much about web development I do not know how to figure out what is going wrong.</p>
  
  <p>Can someone help me figure out what is wrong, and perhaps explain how they figured it out?</p>
