How to create sitemap


I am wondering how to create a sitemap (for internal use) where I can showcase all pages and their connection to eachother? To see which pages are repeated/similar and how they are connected. Is this possible and if so how do I go about it?

I have these instructions but they seem to be more about an external sitemap for google indexing, which isnt really what I am out for How to Add a Sitemap to Your Drupal Website

Thank you very much,

Kind regards,
