Cartogram

http://www.viewsoftheworld.net/data/PaullHennig_2011_EJSS_OrganicAgriculture.pdf

A cartogram communicates relative distance scaling among places in regards to their similarity of a particular attribute rather than measuring by physical proximity. The map above is an equal-density cartogram displaying the density of organic agriculture worldwide. The distribution of organic agriculture is clearly uneven across the world. Illustrated here, Australia has expanded to be multiple times the size of the physical land mass meaning that it's the most common user of organic agriculture per hectare. North America on the other hand looks very similar to it's physical land mass, not appearing bloated at all, showing that organic agriculture per hectare is not the dominate practice within North America. The distance between the the map areas is not absolute but rather relative to the position of the area in its number of organic agriculture hectares.
