How did you do this?

Created the Stats and StatsApplicationGraph components in features.
Added a new "/admin/stats" route for the Stats component.

How to test:

Automatic test at PR.

Questions:

I did not push the changes done by linting since many code that I didn't touch were also changed and there were many errors. Do I need to worry about this?

I had an interface that I would like to share between Stats and StatsApplicationGraph. Is there a good way of doing so? (Currently I just copied the interface over)

You can add & export an interface as a separate file and then import it into both files you want to use it. We do this for other interfaces too!

Thank you Theo! I put the interface in a separate file in the latest commit. Does the export style look correct?
