Polling hubs
The second type of deployment is a polling hub (formerly known as a carousel).

The dots above the question text indicate the polling session's status as the user progresses through the experience.
A polling hub example is shown here. Information about the integration may be found here.
This implementation is typically used on a page where the focus is on the polling experience. Polling hubs are a great way to increase time spent on your site and, therefore, ad revenue.
