For those of us who hope to engage students on issues such as political or economic development, the World Freedom Atlas is a fantastic resource.
Designer Zachary Johnson has created a very slick Flash interface for dozens of datasets (>300 variables) generated by academics, NGOs and IOs on the global distribution of human rights, governance, and development indicators between 1990 and 2006.
WFA not only maps national distributions of each, but also histograms and scatterplots, with the ability to show absolute values vs. change over time.
Can't wait to use it in my intro course.
H/T to information aesthetics for the link.
