Abstract: Interactive information visualization provides researchers with remarkable tools for discovery. By combining powerful data mining methods with user-controlled interfaces, users are beginning to benefit from these potent telescopes for high-dimensional spaces. They can begin with an overview, zoom in on areas of interest, filter out unwanted items, and then click for details on demand. With careful design and efficient algorithms, the dynamic queries approach to data exploration can provide 100 ms updates even for million-record databases. This talk will review growing commercial success stories such as,, and It will then cover recent research progress for visual exploration of large time series data applied to financial, Ebay auction, and genomic data (see Finally, the talk will discuss the combination of these ideas in the Hierarchical Clustering Explorer 3.0 that includes the rank-by-feature framework (see By judiciously choosing from appropriate ranking criteria for low-dimensional axis-parallel projections, users can locate desired features of higher-dimensional spaces. Demonstrations will be shown.
