This page links here to a powerful visualiser which allows the reader to examine the distribution of monetary policy frameworks over time, for different categories of countries, different aggregations of frameworks and diffferent weights (number of countries, GDP, population).
The visualiser was created by Bram Boskamp using a visualisation programme developed using the D3 Javascript library. It seems to be best watched using Google Chrome, but functions with other browsers too.
