A Model for Analyzing and Visualizing Tabular Data

摘要

We present a model to visual analysis of tabular data based on functional dependencies, and a Web based tool that supports casual users in doing the following: (a) construct an analytic query visually, in a flexible, interactive manner, (b) visualize the aggregate result in a user selected mode (histogram, pie, etc.), (c) explore the query result by viewing equivalent representations at different aggregation levels or for different parameter values.
