摘要：

Interactive graphical tools are available in a number of statistical packages. However, none of them provide interactive tools for visual exploration of time series data that have spatial reference (spatio-temporal data), such as census data. Analysis of spatio-temporal data requires simultaneous representation of their spatial, temporal, and thematic aspects. We propose a system that combines interactive thematic maps, dynamic statistical graphics, and advanced controls for manipulating them. These components as well as interaction between them are specifically designed in order to support-visual investigation of changes in data, the ultimate goal being to help users to reveal spatio-temporal trends. The suggested tools facilitate also detecting errors and anomalies in data.
