Comparative multivariate visualization across conceptuallydifferent graphic displays

摘要

To extend the scope of multivariate data visualization, the notionof comparative visualization is introduced: it allows the comparison ofvisualization methods by interconnecting several different graphicdisplays. This linking of visualizations, together with the possibilityto interactively manipulate data, enable an analyst to display the samedata set with a number of conceptually different visualization methodssimultaneously and to carry out graphical operations across them.Graphical effects in different displays not only reveal informationabout the data themselves, they also provide the basis to investigatehow the different visualization methods relate to each other. With the“VisuLab”, we developed a software tool for personalcomputers to investigate comparative multivariate data visualization
