A dot is one abstraction the document touched, placed at its fixed position on the Abstraction Atlas.
Large = core, small = supporting.
A split dot was hit by two different documents — the same abstraction wearing two sets of clothing.
An outlined shape is a territory: a named cluster of related abstractions. Lit outline = the x-ray
landed inside it. Everything faint in the background is the rest of the encyclopedia.
A line is a relationship in the corpus DAG between two of your hits, and the arrow gives its
direction: A → B reads "A presupposes B" or "A is part of B" — the arrow
points at the more foundational side. Lines appear when you hover a dot or highlight a territory
(or turn on "All DAG edges"); each relationship is spelled out in the dot's pop-up.

Position is meaningful: the atlas places related abstractions near each other. A tight bundle means
the document lives in one neighborhood; a scatter across continents means it draws on many.
"Atlas context" shows the rest of the map — its remaining territories and the 14 continents,
named around the edge with dotted leaders in each continent's color. Click a continent's name
to highlight everything the x-ray touched inside it.

Hover a dot for its evidence — which passage put it there; click it to pin the pop-up and open the
entry on abstractopedia.org. Click a territory (map or list) to highlight it, or click a document name
(legend or list header) to light up everything that document touched — the view stays put, nothing jumps.
