Social Explorer also offers time-series maps for New York City and Los Angeles County. These allow users to follow trends in distributions of races over time.
Those interested in mapping something other than Census data might try the National Atlas Map Maker, which allows you to map data on agriculture, the environment, recent elections, etc.
