Unit´e de recherche INRIA Futurs The InfoVis Toolkit Jean-Daniel Fekete Th` eme 3 — Interaction homme-machine, images, donn´ ees, connaissances Projet IN-SITU Rapport de recherche n 4818 — Mai2003 — 11 pages Abstract: This report presents the InfoVis Toolkit , designed to support the creation, extension and integration of advanced 2D Information Visualization components into in- teractive Java Swing applications. The InfoVis Toolkit provides specific data structures to achieve a fast action/feedback loop required by dynamic queries. It comes with a large set of components such as range sliders and tailored control panels required to control and configure the visualizations. These components are integrated into a coherent framework that simplifies the management of rich data structures and the design and extension of visualizations. Supported data structures currently include tables, trees and graphs. Sup- ported visualizations include scatter plots, time series, Treemaps, node-link diagrams for trees and graphs and adjacency matrix for graphs. All visualizations can use fisheye lenses and dynamic labeling. The InfoVis Toolkit supports hardware acceleration when available through Agile2D, an implementation of the Java Graphics API based on OpenGL, achieving speedups of 10 to 60 times. The report also shows how new visualizations can be added and extended to become components, enriching visualizations as well as general applications. Key-words: Information Visualization, Human-Computer Interaction, Toolkit, tables, trees, graphs

La boˆ ıte ` a outils InfoVis esum´ e : Ce rapport d´ ecrit la boˆ ıte ` a outils InfoVis , con¸ cue pour faciliter la cr´ eation, l’extension et l’int´ egration de composants de visualization d’information 2D avanc´ es dans des programmes interactifs Java Swing. La boˆ ıte ` a outils InfoVis offre des structures de donn´ ees optimis´ ees pour que la boucle action/perception des requˆ etes dynamiques soit aussi rapide que possible. Elle fournit un ensemble riche de composants tels des barres de r´ eglage d’intervalles ainsi que des boˆ ıtes de r´ eglages permettant de controler et configurer les visua- lisations. Ces composants sont int´ egr´ es dans un cadre coh´ erent qui simplifie la gestion de structures de donn´ ees riches et la conception et r´ ealisation de visualisations. Les structures de donn´ ees actuellement g´ er´ ees sont les tables, les arbres et les graphes. Les visualisations disponibles sont les diagrammes de points, les s´ eries temporelles, les treemaps, les diagrammes noeud- liens pour les arbres et les graphes et les matrices d’adjacence pour les graphes. Toutes les visualisations peuvent utiliser des lentiles d´ eformantes (Fisheyes) et des labels dynamiques.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
