The Trade Space Visualizer is a data visualization

Data visualization

Data visualization is the study of the visual representation of data, meaning "information that has been abstracted in some schematic form, including attributes or variables for the units of information"....

The Pennsylvania State University, commonly referred to as Penn State or PSU, is a public research university with campuses and facilities throughout the state of Pennsylvania, United States. Founded in 1855, the university has a threefold mission of teaching, research, and public service...

. 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

Java (programming language)

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

-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.
