There's a great article that shows how to copy a dashboard someone else built, so you can learn the configurations of it.
Is such workflow possible with Experience Builder?
I don't think this type of workflow is possible on EB. In fact, EB is build for web services (or web "experience") but for complex and detailed statistic dashboard like them.
I don't see any current defaut widget be able to create some dashboard as complex as we can see in your link. So, maybe you'll need to create a custom widget which simply display the dashboard you want ?!
