Embeddable widget
It would be very neat if instance admins could embed a widget on their instance's About page.
This widget would show the fediverse.space graph but filtered down to the instance in question. Users can have basic interactions with the widget (dragging to move the graph) and click through to the full fediverse.space website.
Mastodon About pages support iframes, as shown by the fact that you can embed YouTube videos. I am not sure whether Pleroma supports this, but Pleroma's About pages also tend to be more hidden. Unlike Mastodon, they aren't shown first thing when you visit an instance.
