The Trade Space Visualizer is a data visualization tool developed at the Applied Research Laboratory (ARL) at The Pennsylvania State University. Initial development started in 2002, and it is currently supported by a team at ARL/Penn State.
Overview
The Trade Space Visualizer is a Java-based tool that includes multidimensional visualization techniques to display data files. The interface can load data in tabular format (.txt or .csv format). Recent work has focused on using the interface to drive underlying simulation models, by allowing users to place visual steering commands within data visualization plots.
