The improvement of data storage devices and means to collect data has lead to accumulated data sources and there is a need for effective methods to extract knowledge from them. Visual analytics is one approach to tackle this information overload problem. It has been defined as "the science of analytical reasoning supported by the interactive visual interface". It provides visual tools to support analytical reasoning and decision making from data with interactive visualizations. This report presents the findings of the joint project by VTT, TKK and Helsinki Institute of Information Technology (HIIT) around the topic in 2008. The report introduces the concept, the state-of-the-art of research and tools on the markets, presents the demonstration tool developed in the project and outlines roadmaps for industrial and consumer applications.
