I’ve recently discovered a very good example of information visualization. It is created by HSBC and lets the user explore and compare countries based on various criteria and the data come from people who’ve been to those countries as foreigners:
The Expat Explorer survey, now in its third year, is the largest independent global survey of expats. Commissioned by HSBC Bank International and conducted by a third party research company, more than 4,100 expats based in 100 countries across the globe were questioned between April and June 2010.
The above map shows compares the countries according to the ‘Healthcare access and quality’ index, e.g. the bigger the bubble the easier to access healthcare and higher the quality. I think this is a very useful tool for people who think about living and working abroad. Moreover, it stands as a very good example of information visualization as well as user experience design.
