title: How to use paper-dialog polymer element?
body: <p>I am using the element by adding opening and closing tags <code>&lt;paper-dialog&gt;&lt;p&gt;This is it&lt;/p&gt;&lt;/paper-dialog&gt;</code> but it is not getting shown up. Do I need to add some script on top of it so that it should be triggered on some event? Or is there some another way to make it visible ?</p>
