There are many templates to choose from in Joomla. You can an idea of how many by checking out Best of Joomla.
I like using the templates from JoomlaShine. They are easy to customize mobile ready. And they all use the same map.
Here is a selection of templates that they offer.....
Each of there templates uses the same map and shows all the module positions. The modules give you the flexibility in design telling what information you want on what page. The red arrow shows where the articles (pages of the website) go. The rest are module positions.
