Using the release of the “Muslim Populations By Country” dataset from the Guardian Datastore I have produced a cartogram to visualise the data. The size of the country represents its 2010 Muslim population and the colours indicate how much the population is expected to grow/ shrink over the next 20 years. It may not be interactive but it is a really compelling way to show the data. It would be good to get hold of data for other religions. For more cartogram fun check out Worldmapper.
