The Library Card platform has a metrics dashboard. We stopped using much of the data on it in favour of more fine-grained data such as that from the EZProxy logs. Additionally, it stopped loading some time ago (T237721). It hasn't been displayed to users in the navigation bar for a while either.
We have determined that, given that we don't need the metrics dashboard, we can simply remove the entire graphs app. There are a handful of related areas of the codebase which can also be removed, such as the django-requests module.
