Thinking about the map. In cases where it is impossible to project cleanly down to 2 dimensions, like you could with this Strava heatmap:
Adding elements like ‘highways’ (wormholes?) connecting two distant points might make sense. In this way, the larger dimensions are preserved, and the unusual relationships are still visible. In the case of language vs semantics, this could show the connections of ‘Java’ as a computer language, beverage, and country:
There are several ways of looking at these projections too. I would think that a map made entirely of long haul air routes would project differently than roads. It should be possible to ‘morph’ between these projections to explore the relationships.
