Pretty cool apps! One thing i'd love to see for both is a historical view of the data - how do things change over time? Where is today relative the past five years for a given place? ten years? etc.
But you're right that it'd make sense to have an aggregate view on the level above (e.g. https://the-dwell.com/anchored). I shall go command Fable to figure out all the places where this would be appropriate and add it.
