The cartography package allows various cartographic representations
such as proportional symbols, chroropleth, typology, flows or discontinuities.
In addition it also proposes some useful features like cartographic palettes,
layout (scale, north arrow, title…), labels, legends or access to cartographic
API to ease the graphic presentation of maps.A vignette contains commented scripts on how to build various types of maps
with cartography:
