If you're into data analysis and visualisation but not quite ready to invest in one of the more professional business intelligence tools such as Tableau and Spotfire (contact us if you want to find out more), then you should check out Google Fusion Tables.

Apart from being free (all you need is a Google account), Google Fusion Tables allows you to import your data, visualise it using a slection of charts (the interactive maps are especially cool, see below) and publish reports on your own website that users can interact with via filters. Have a look at the below fusion table from the WHO on global tuberculosis control and hover over some of the countries.
