JavaScript. Opening window with some content
<p>I'm new to JavaScript, so I've a question about it. I tried to google, but didn't find any information. So. I need to open chart in a new window, but not in browser window, in some kind of a custom window. So what's the idea. There is some element on a page, for example image. And when user clicks on it, chart appears in a custom window. </p>

<p>Here's the example: <a href="http://canvasjs.com/javascript-charts/" rel="nofollow">http://canvasjs.com/javascript-charts/</a>. As we can see, when we click on "Simple Column Chart" image, some kind of a window appears (but it's not a browser window, as I assume), and there's desired chart on this new window.</p>

<p>So my question is, how to implement such thing, when user clicks on some element and window (not browser window) with something (chart, in this case) appears? </p>
