I came across these pie charts today and think they are delightful, not least because they look like something Alexander Calder might have painted. The charts are direct comparisons of children's imaginations to scientific data. Researchers asked children in England to draw their ideal rainforest and then the number of different species was quantified. The chart on the left is the biomass of diversity in tropical rain forests as represented in their art work; the middle and right side charts are actual scientific measurements.
