Scale and Complexity in Visual Analytics

George Robertson, David Ebert, Stephen Eick, Daniel Keim, Ken Joy
2009 Information Visualization  
There is a growing impedance mismatch between data size/complexity and the human ability to understand and interact with data.  ...  Visual analytic tools are intended to help reduce that impedance mismatch by using analytic tools to reduce the amount of data that must be viewed, and visualization tools to help understand the patterns  ...  This is the information scalability problem; how do you extract the relevant data from a massive stream of data?  ...

Scalable Visual Data Exploration of Large Data Sets via MultiResolution

Daniel A. Keim, Jörn Schneidewind
2005 Journal of universal computer science (Online)  
Most existing visualization metaphors and concepts do not scale well on such large data sets as interaction capabilities and visual representations suffer from the massive number of data points.  ...  During the last decade Visual Exploration and Visual Data Mining techniques have proven to be of high value in exploratory data analysis since they combine human visual perception and recognition capabilities  ...  We believe, that for the analysis of massive data sets, it is not sufficient to just retrieve and display the data using a visual metaphor, it is rather necessary to support the analyst by filtering the  ...
