I find that it's useful not just to look at the current contents of codebase, but how it has evolved over time. For example, after being onboarded, this lets me see where most of the current effort on a codebase is concentrated and what the biggest recent changes have been.

For this, i believe that Gource is a lovely tool, which you can just point at a Git repository and it will visualize it: https://gource.io/
