Plot of the Day. The Netherlands has a very fine grained and in many senses very good postcode system. People often try to use postcodes for geographical purposes, to cluster precincts. The PC system however is not meant for that. Here convex hulls around all 3 digit prefixes, which often overlap:

Convex hulls around all 3 digit postcode prefixes, which often overlap, but form a pretty map of The Netherlands.

Same graph, but now for 4 digit prefixes:

This plot by the way was made by feeding 7 million or so house shapes into boost::geometry & asking it to draw convex hulls around dwellings sharing the same 3-digit prefix postcode. boost::geometry is pretty bad ass. #C++
