I’ve seen many places talk about how to get page insights from within a facebook application. I am trying to show user’s page’s insights on my websites with my graphing tools without an application.
I can have them provide login information, or if I need to connect my website with them, etc. etc., I can do that. Does anyone know how I would go about getting this information?
Look at the read_insights permission.

Your flow would be to ask the user to connect to your app and ask for the read_insights permission. Once you have the access token, you can query the data of their domains/pages/apps.
