Hello Vaibhav,
The reference you have shared is from dashboard view as a reader and not author.
Its for reader -pro to have the insight and keep the visuals insight as pinboard.
Within Analysis ( build Visuals), you will get only one visual at a time which can be added to Analysis sheet and later can be publish as dashboard.
if you click on Dashboard page, you get Ask a question about …(your topic) and thus you see the insights as your screenshots.
Hope this clears some doubt.
cheers,
Deep
