Tom Sawyer Software Releases Upgraded Pure Java Visualization Software

Tom Sawyer Visualization, Version 7.0, Java Edition, Introduces New Patent Pending Circular Layout and Dramatic Symmetric Layout Performance Improvements

Oakland, CA, May 13, 2005—Tom Sawyer® Software, a leading provider of high-performance graph visualization, layout, and analysis solutions, today released Tom Sawyer Visualization, Version 7.0, Java Edition, the latest of its visualization product line.

The Tom Sawyer Visualization product line delivers sophisticated component technology that manages, reveals, and displays graphical and customized views of relational data, immediately identifying relationships, connections, and emerging patterns within the data. The software displays pathways, models, flows, dependencies, networks, and schematics in a comprehensive visual format.

New Features

Tom Sawyer Visualization, Version 7.0, Java Edition, offers significant new features and feature enhancements. Some highlights include:

System

Graphics

Rendering

Interactive Environment

Layout

  • Circular layout
  • Symmetric layout
  • Hierarchical layout
  • Orthogonal layout
  • Improved labeling
  • Enhanced nested diagram layout
  • Added Benefits

    The latest release of Tom Sawyer Visualization delivers a newly modularized software architecture. With this new architecture, you may configure your application with viewing support, or with both viewing and editing support. This allows you to reduce the size of your application or applet if you have data-driven architectures that only require viewing support.

    The new version includes a separation between the graphical drawing and the device on which a graphical drawing is rendered. Also, it is now possible to plug in different graphical devices such as different drawing canvases, printer or image export devices.

    This new design enables you to write a single code base for graphical drawings that supports both thick and thin client application development. You can use Tom Sawyer Visualization, Java Edition for thick client application development, and the new Tom Sawyer Visualization, JSP Edition for thin client application development.

    The new version has JDK 1.5 support and Eclipse SWT support, requires less memory usage, and has greatly expanded documentation and source code tutorials.

    The latest release of Tom Sawyer Visualization provides a new patent-pending implementation of circular layout. This new implementation provides greatly improved clustering, circular-shaped clusters, node placement within clusters, and either circular or symmetric backbone placement. The implementation also includes a highly stable form of incremental layout.

    Improved clustering reveals the underlying network structure much more effectively than before. The new node placement within clusters guarantees an appealing circular shape for each cluster. Further, nodes are automatically placed within each cluster under certain conditions based on their connectivity to other nodes on the interior and exterior of a cluster. The new interior node placement reduces the radius of many clusters and enables drawings of smaller overall area. As the area of a drawing is reduced, it becomes simpler to view the text within labels and to navigate the drawing.

    The new release brings dramatic performance improvements in symmetric layout, two and a half times faster than the previous version. This is especially beneficial to applications with large graphs such as those found in networking, life sciences, and intelligence.

    Additionally, this release includes significant enhancements in our labeling technology. Now labels are considered during the layout process when edges are routed orthogonally. This integrated approach optimizes the overall placement of nodes, labels, and edge routes, providing clear and comprehensive drawings. Connector labeling has also been enhanced in this release.

    Further, this release introduces a new approach to nested layout. During the layout process, the entire nested diagram structure is considered all at once. This enables better overall node placement and shorter edge routes. The new process also improves the layout quality with mixed routing styles.
