The Evolution
of a Cartogram
of Population
by County
Figure 3.3 Ten stages in the development of a cartogram based on the 1981
census populations of 64 counties are shown, illustrating the mechanics of some of
the software. The picture gives an idea of the dynamics of the cartogram algorithm
and the interplay of each area pushing for space. The West Midlands circle in the
centre can be seen to have hardly moved at all.
