Cool data visualization pages are proliferating all over the web.

Probably the most graphically stunning is A Handsome Atlas  from Brooklyn Brainery, with colorful and imaginative visualizations of 19th century U.S. census data.

Rich Blocks, Poor Blocks has taken data from the US Census Bureau’s 2007 through 2011 American Community Survey to map  income data on income and rent. Data can be displayed by street address, zip code, census tract number, or city, and comparisons to state medians are also shown.

Gapminder bills itself as  “a non-profit venture – a modern “museum” on the Internet – promoting sustainable global development and achievement of the United Nations Millennium Development Goals.”  Its data page contains visualizations on 513 socioeconomic indicators by country. The same data is also available to download to spreadsheets. The rest of the site is also worth checking out, particularly the Joy of Stats documentary.
