Figure 9.11 A later period is shown here, with similar numbers of incidents
of childhood cancer, again on a population cartogram base. The image appears
larger than before because the cases are nearer in time, although individually
cases are all the same size. Coming closer to the present there are again no clear
patterns, but, again, from this angle, a possible grouping of cases in Teeside is
seen. Note that the banding of grey-shades at the foot of both these figures is
due to the original low screen resolution and limited pallet for colours that the
software could use.
