Plot.io is a new web-based software that helps you visuliaze, plot and make sense of large amounts of data, without requiring you to download, install or setup any software at all (no Flash, Silverlight, Java or plug-ins required).
You simply point to an existing database resource or upload a text file and Plot.io immediately reads all your data while providing you with intuitive and easy to use tools to visualize it.
As a matter of fact there are nearly limitless visualization possibilities available to the user.
See many examples of data infographics that can be created with Plot.io in this video (starting at 2'): http://www.youtube.com/watch?v=4m2ywMAlT-M&feature=related
Visualizations created with Plot.io can also be easily shared and published on the web.
