Figure 2B is a part of a Swedish topographic map from around 1815, made
by plane tabling, drawn on sight (but redrawn afterwards). The drawn
maps were geodetically positioned by astronomic measurements; other-
wise it would qualify to a position in the corner of the diagram (i.e. based
entirely on visual observations).
Figure 2C is a topographic map from 1984. It is based on aerial photo-
graphs, which were rectified, interpreted and completed with terrestrial
measurments. The visual contents of the map are dominating yet the inter-
pretation and treatment of this information is indirect. The map contains
important abstract information as geographical names, administrative
boundaries and grid net. Hence the map is balanced between visual and
abstract components which defines its position in the approx. middle of the
axis

Figure 2D is a thematic map on the population in the city of Malmoe in
southern Sweden. The base map shows the building blocks of the city and
some large parks, but it is dominated by the boundaries of the districts for
statistical purpose and the pie charts showing the composition of the popu-
lation. The maps content is dominated by abstract information. Hence the
dot representing it is close to the corner “Abstractions”.
Figure 2E and figure 2G was analysed previously. Figure 2F is new, how-
ever. This is a part of a map, depicting an imaginary landscape of mathe-
