To be most useful, evaluation requires detailed observation and effective analysis of a full spectrum of system use. We have developed an approach and architecture for in-depth data collection and analysis of all use of a visualization system. User interface components in a large visualization and analysis platform automatically record user actions, and can(More)
Fig. 1. The data flow graph for a reactive bar chart based on reactive models, the core contribution of this paper. Abstract—Managing complex data flows and update patterns is one of the most difficult challenges in interactive data visual-ization. For example, constructing interactive visualizations with multiple linked views can be a daunting task.(More)
To be most useful, evaluation metrics should be based on detailed observation and effective analysis of a full spectrum of system use. Because observation is costly, ideally we want a system to provide in-depth data collection with allied analyses of the key user interface elements. We have developed a visualization and analysis platform [1] that(More)
We introduce a novel interactive visualization technique for semantic networks supporting continuous semantic graph browsing. Our visual semantic graph representation is a nested object visualization representing a view into the graph from a node's viewpoint. In this view, panning and zooming interactions drive graph traversal. We call the visualization(More)
