The New York Times, known for some first-class infographics and data visualizations, released this thought-provoking map of food stamp usage in the United States, on a county-by-county basis. In addition to the county-level statistics, there are a number of call-outs and a related article.
One feature I thought was interesting, in addition to the elegant interactive map, was the sortable data table view of the underlying dataset. Even cooler, if you don't feel like using the sortable dataset, the designers of the infographic have helpfully provided a link to download the raw underlying data itself in CSV format, so that you can analyze it yourself in OpenOffice.org Calc or Microsoft Excel! Three cheers for open journalism.
