The World Bank eAtlas of the Millennium Development Goals lets you visualize and map the indicators that measure progress toward the Goals, with clear explanations of each Goal and its related Targets as the context. When you select an indicator, the eAtlas creates a world map keyed to that indicator, with country rankings and data in your choice of tables or graphs. You can pan or zoom to view different countries or regions, view the dynamic change in that map with a time series, compare two maps and sets of data, and do much more.
