Using hexograms to map areal data

This paper introduces hexograms as a method for mapping areal data. It builds on the idea of balanced cartograms that reduce geographic distortion, combining those with hexagonal binning to create non-tessellating tile maps of geographical distributions. The aim is to produce less geographically distorted
representations of neighbourhood and other areal data than those resulting from conventional cartograms, whilst also avoiding the problem of invisibility found in traditional choropleth maps. The process behind the method is introduced with examples of its application. The code to reproduce some of the maps is available for R.
