If you are interested in economic development, cross-country comparisons and data visualization this new facility from the World Bank is useful.
And to complete the toolkit a new stata module WBOPENDATA draws from the main World Bank collections of development indicators, compiled from officially-recognized international sources, and made available through the World Bank Open Data Initiative, and presents the most current and accurate global development data available, and includes national, regional and global estimates.
User's can download WBOPENDATA directly from within Stata by typing
