Multidimensional data visualization.
Historically, data visualization has been limited primarily to two dimensions (e.g., histograms or scatter plots). Available software packages (e.g., Data Desk 6.1, MatLab 6.1, SAS-JMP 4.04, SPSS 10.0) are capable of producing three-dimensional scatter plots with (varying degrees of) user interactivity. We constructed our own data visualization application with the Visualization Toolkit (Schroe...
متن کاملData Visualization With Multidimensional Scaling
We discuss methodology for multidimensional scaling (MDS) and its implementation in two software systems, GGvis and XGvis. MDS is a visualization technique for proximity data, that is, data in the form of N × N dissimilarity matrices. MDS constructs maps (“configurations,” “embeddings”) in IRk by interpreting the dissimilarities as distances. Two frequent sources of dissimilarities are high-dim...
متن کاملInteractive Visualization of Multidimensional Data
Interactive data visualization concerns the real time manipulation of sampled and computed data for comprehensive display. The goal of the visualization is to bring to the user a deeper understanding of the data as well as the underlying physical laws and properties. In this survey paper I focus on two problem areas relating to interactive data visualization. The rst is in data reduction and de...
متن کاملPoster: Multidimensional Visualization of Hemodynamic Data
The Multiscale Hemodynamics Project is a collaboration of doctors, physicists, and computational scientists working together to model human blood flow through the coronary arteries. Having effective visualizations of the simulation’s multidimensional output are vital for the quick and thorough evaluation by a cardiologist. A user study was conducted to evaluate the utility of various methods fo...
متن کاملLarge multidimensional data visualization for materials science
How does a crack propagate in a composite material? How does a highspeed projectile interact with its target? And how can we use this knowledge to make fractureand impact-resistant materials? Materials science poses such questions, and we can answer them by simulating materials on supercomputers and analyzing their properties. Scientific visualization is an excellent tool in this analysis, and ...
