The World Bank produces a mash-up of Google Maps with World Bank data to give a visual entry point to browse World Bank projects, news, statistics and public information by country - http://geo.worldbank.org/.
The OECD eXplorer developed jointly by the OECD and the National Centre for Visual Analytics at Linköping University, Sweden, combines maps and graphs with stories http://stats.oecd.org/oecdfactbook/.
Alternatively, you can upload data from spreadsheets or csv files into Google Fusion Tables and view the data on a map or as a chart immediately. Columns with locations are interpreted automatically, and you can adjust them directly on a map if necessary. However, please be aware of the End User Licence conditions and any dataset specific Special Conditions which you will have agreed to when accessing ESDS International data.
