Many Eyes: (visual) social data analysis from IBM
IBM guys launched Many Eyes a "social data analysis" visualization software. Users can upload data, create visualizations and share it online.
A series of common visualization techniques are provided (e.g., maps, barcharts, treemaps, etc.).
In the authors' words:
Many Eyes is a bet on the power of human visual intelligence to find patterns. Our goal is to "democratize" visualization and to enable a new social kind of data analysis.
