Stylised Choropleth Maps for New Zealand Regions and District Health Boards
Thomas Lumley · arXiv (Cornell University) · 2019
New Zealand has two top-level sets of administrative divisions: the District Health Boards and the Regions. In this note I describe a hexagonal layout for creating stylised maps of these divisions, and using colour, size, and triangular subdivisions to compare data between divisions and across multiple variables. I present an implementation in the DHBins package for R using both base graphics and ggplot2; the concepts and specific hexagonal layout could be used in any software.
