Nathan Yau of Flowing Data points to a rendering of the subject area physics as a geographic map.
Somewhat dated (1939) but shows a lot of creativity and not small amount of cartographic skill.
Rather than calling it a “fictional” map I would prefer to say it is an intellectual map of physics.
Like all maps, the objects appear in explicit relationships to each other and there are no doubt as many implicit relationships are there are viewers of the map.
What continuum or dimensions would you use to create a map of modern ontologies?
That could make a very interesting exercise for the topic maps class. To have students create maps and then attempt to draw out what unspoken dimensions were driving the layout between parts of the map.
Suggestions of mapping software anyone?
