        When you have a lot of points and only want to show one popup at a time, the best approach is to create one popup and reuse
        it rather than creating a popup for each point feature. By doing this the number of DOM elements created by the application is greatly
        reduced which can provide better performance. This sample creates 3 point features. If you click on any
        of them, a popup will be displayed with the content for that point feature.
