Polyspector™: An Interactive Visualization Platform Optimized for Visual Analysis of Big Data

With the advent of the 'big data' era, there are unprecedented opportunities and challenges to explore complex and large datasets. In the paper, we introduce Polyspector, a web-based interactive visualization platform optimized for interactive visual analysis with two distinguishing features. Firstly, a visualization-specific database engine based on pixel-aware aggregation is implemented to generate views of hundreds of millions of data items within a second even with an off-the-shelf PC. Secondly, a novel deep-linking mechanism, combined with the pixel-aware aggregation, is exploited to realize interactive visual analysis interfaces such as zooming, overview + detail, context + focus etc.
