https://public.tableau.com/ is a great repository! I usually go there when I want to look at how people around the world is using the tool, both in a general sense or for a particular type of analysis. Not too long ago, a co-worker of mine put together a blog post that uses some of the data points you describe: Using Tableau's Clustering Feature with Map Layers to Get the Full Picture | Tableau Public. More that being just a dashboard, it tells a story.
Hope this helps!
