Highcharts won't display in Chrome App

I am trying to embed a chart from highcharts.com (using jquery). The graphs works fine if I just open windows.html in chrome itself, but it will not load in my chrome app. Just a blank screen. I have all the standard .js files in the folder, but didn't include them here.

I started with the example here: https://developer.chrome.com/apps/first_app

background.js

chrome.app.runtime.onLaunched.addListener(function() {
  chrome.app.window.create('window.html', {
    'bounds': {
      'width': 400,
      'height': 500
    }
  });
});

manifest file:

{
  "name": "Hello World!",
  "description": "My first Chrome App.",
  "version": "0.1",
  "manifest_version": 2,
  "app": {
    "background": {
      "scripts": ["background.js"]
    }
  },
  "icons": { "16": "calculator-16.png", "128": "calculator-128.png" }
}

window.html

The answer is in this JSFiddle: http://jsfiddle.net/jarrodek/sdr57h3g/

<body>
    <!-- Firstly show content, the app will looks more responsive -->
    <div id="container" style="min-width: 200px; height: 200px; margin: 0 auto"></div>
    <!-- now you have content loaded and you can execute you code -->
    <script type="text/javascript" src="jquery.min.js"></script>
    <script src="highcharts.js"></script>
    <script src="exporting.js"></script>
    <!-- move your code to external file (panel below) -->
    <script src="myapp.js"></script>
</body>

Now you can be sure that all dependencies has been loaded before your code run.
