Take, for example, their 'In-Depth Look At USA's Religious Beliefs, Practices' interactive flash feature.
The graphics allow users to slice and dice data from the Pew Forum on Religion and Public Life's US Religious Landscape Survey. While the Pew Forum's site does have some neat interactive features (and is certainly worth checking out), the USA Today graphics serve the data up a bit differently, with breakdowns of survey responses broken down by religious affiliation, as well as a compelling topography of American faith. Users can view data for each state by clicking the state on the map.
The results often serve to confirm stereotypes: The southeast contains a large population of Evangelicals, the Northeast and the West coast have the larger 'unaffiliated' populations, and Utah is full of Mormons.
Also worth checking out are USA Today's interactive feature on shifting religious identities and their test on religious knowledge.
