okay so here's a weird question. scott mccloud's "big triangle"— https://wordsonplay.com/2009/10/the-big-triangle/ is there a general term for this kind of thing? a space with extremes where items in the space are annotated with illustrations/representations whose position in the space corresponds to the extent to which the properties at the extremes describe them?
e.g., eadweard muybridge photo illustrations (if you unwrapped them into a single line) http://www.eadweardmuybridge.co.uk/ would be a one-dimensional example of this (where the dimension represents time); t-sne visualizations would be another example (where the dimensions don't have a set meaning) https://lvdmaaten.github.io/tsne/ maybe even the periodic table of elements would qualify https://en.wikipedia.org/wiki/Periodic_table (though in that case the "representations" are just the names of the elements)
(the unifying characteristic here being that with any of these methods you could—at least conceptually—"interpolate" between two items in the space in order to invent/discover a new item at the point between them)
the new york magazine approval matrix is another example http://nymag.com/arts/all/approvalmatrix/approval-matrix-2017-03-20/
