Tom Sawyer Perspectives, Java Edition

 Show Releases

Release 13.2.0

Date	February 26, 2025
Status	General

Overview

This release highlights improvements to the Modern web client framework, which is now the default framework for Perspectives applications, featuring rearranged default toolbars in our views and updated action icons. Key updates include that our chart and timeline views now have a React-based underlying framework. Other improvements are: REST support, Print Preview support, Cancel Layout operation, invokable view dialogs, and HTML dialogs. New tutorials show how to use Tom Sawyer Web Components in Angular or plain HTML web applications. End users now have the ability to enter custom Cypher or Gremlin queries directly in their application. Performance speed of schema extraction has been significantly improved for graph databases.

Hierarchical layout has been improved to reduce edge crossings up to 30-50% on average, and also improved node placement and edge routing given the flow of edges in the drawing. The implementation of Closeness Centrality has also been improved for disconnected graphs.

Perspectives has been upgraded to Spring Framework 6.2.2 and Spring Boot 3.4.2. Also, many third-party libraries have been updated to eliminate potential vulnerabilities.

Release 10.0.0

Date	September 8, 2021
Status	General

Overview

This release features architectural changes that strengthen the power and performance of Tom Sawyer Perspectives. The integrators for Amazon Neptune, Microsoft Azure Cosmos DB, Neo4j, OrientDB, and Apache TinkerPop can now automatically bind query results to elements in the model. This lets you visualize and explore the data in a graph database without having to create a schema or manually define the data bindings. The new native graph in-memory model supports more effective interaction with graph databases that matches the structure of the data. The model includes fast access to related model elements without the need for lookup functions, and provides a greatly simplified way to create a drawing view from your data without the need to manually define IDs for edges' end nodes.

The new interactive schema editor allows Designer users to easily view and update the schema for Perspectives applications and supports both vertex and edge element types. The improved support for schema inheritance includes generalization, multiple inheritance, and redefinition. There is also a new schema code generator that can take a schema as input and generate a Java domain object model to support faster creation of custom application code.

The in-memory model itself has become more powerful with additional support for vertex and edge types, Reactive Streams for events, stream traversals, native support for graphs, model evaluation functions to perform operations on the native graph model, and serialization in both JSON-LD and BSON. And there is a new TSModel REST view for improved interoperability between Perspectives server-side components and other Tom Sawyer Software or third-party components. All these additions make it faster and easier to get a new Perspectives application up and running.

In the Designer, when adding a graph, analyzer, or view, the user now selects the relevant domains—collections of model elements with filter-style conditions—and adds actions to the domain rules. In the drawing view, disconnected nodes can be sorted by name and there is improved routing for intergraph edges. When defining an inspector view, a user can choose to include attributes dynamically at run time, explicitly select from the schema-defined attributes, or do a combination of both.

In Business Process, rich text documents as well as links to file paths and URLs can be attached to process tasks in the Execution module. Also, users can now retrieve the direct URL of process instances for easier sharing.

Release 8.1.0

Date	April 18, 2018
Status	General

Overview

This release introduces Tom Sawyer Graph Database Browser as part of the Tom Sawyer Perspectives product family. This new solution visualizes the data in a graph database and allows users to browse and interact with that data without the need for writing custom code. Our Graph Database Browser is the first and only end-to-end visualization application that works directly with Amazon Web Services (AWS) Amazon Neptune — a new fully-managed graph database service — and Neo4j where users can see, analyze, and validate their data in graph databases.

With Version 8.1, you can immediately build graph visualization applications for Amazon Neptune databases with the dedicated data integration available in the Tom Sawyer Perspectives Designer.

Tom Sawyer Graph and Data Visualization has been extended with support for graph analysis algorithms integration into the Tom Sawyer Perspectives Designer without the need for writing custom code. Tom Sawyer Perspectives Designer users are able to define configuration options for the analysis algorithms and see real-time results in a drawing view.

Connector support has been improved in Tom Sawyer Graph and Data Visualization to include fixed-size connectors with slope-end routing, variable-sized connectors that automatically grow with the number of edges that are attached to them, and connectors nested within other connectors. These additional forms of connector support allow for more customized drawing views of complex structures. In addition, layout of connectors takes into account the labels of incident edges and connector labels and allows the connectors to grow accordingly. In addition, Version 8.1 has made a 65% speed improvement in the layout of nested graphs with many interdrawing edges.

Tom Sawyer Business Process now displays a process map that provides a high-level view of the processes you have defined and the relationships between these different processes. This release also provides a tree view filtering option that makes it easier to find information. The Business Process application now includes enhanced document linking and search capabilities.

Status	General

Overview

This release introduces play and pause media controls to the timeline view so that users can observe how data evolves over time. The user can choose to play the animation from the left side, right side, or both sides at the same time. We now also include more than a dozen chart types in the charting package.

Tom Sawyer Perspectives now offers a set of options to calculate a polished final viewport that easily animates from the initial viewport to the final viewport. We provide users with smoother transitions after global layout, incremental layout, or complexity management operations.

This release introduces a new one-line diagram layout for the Utilities market that is designed to scale to hundreds of thousands of nodes and supports geospatial hinting, nesting, constraints, and incremental layout.

The Tom Sawyer Perspectives core system has been optimized for performance. The system is up to 30% faster for multi-core and hyper-threaded server configurations.

Release 7.0.0

Date	July 17, 2015
Status	General

Overview

This release introduces charting. It is now possible to add chart views to Tom Sawyer Perspectives web applications through Designer configuration.

A UI Editor has been integrated into the Tom Sawyer Perspectives Designer so you can create composite UIs more easily. You can now create complex UIs for drawings, nodes, edges, labels, and connectors visually with the UI Editor instead of creating UIs programmatically.

Data integration has been greatly improved by adding a new JSON data integrator, adding support for the latest Neo4j 2.2 releases, and improving XML data integration performance by as much as thirty-five percent.

This release also introduces new tools for viewing and editing. The new modeless Select and Pan tool unites the functionality of the Select tool, Pan tool, and zooming tools to eliminate the need to switch between tools. The Move tool can transfer drawing objects from one nested drawing level to another nested drawing level. Further, Tom Sawyer Perspectives adds a Reconnect Edge tool for use in web applications.

Additionally, this release adds support for visually representing edge crossings.

For those who use Maven, Tom Sawyer Perspectives has been fully mavenized with a public Maven repository for downloading new releases.

Finally, this release offers many new performance and quality enhancements.

Release 6.2.0

Date	July 31, 2014
Status	General

Overview

Tom Sawyer Perspectives now provides a new REST data integrator. The new integrator can connect to RESTful web services, populate a schema, and process the resulting JSON or XML streams into Tom Sawyer Perspectives models.

Additionally, HTML5 performance has been improved through reduced data traffic and updates during animation.

This release also introduces an option to rotate edge labels so that they run parallel to their associated edge segments. This allows for more readable drawings, especially for the straight-line layout styles with bundles of multi-edges. Lastly, a smart bend removal algorithm has been added that eliminates some unnecessary bends in an orthogonal drawing.

Several new preferences have been added to allow for a more flexible, customized experience of your applications.

Overview

Tom Sawyer Perspectives introduces an advanced data-driven graphics architecture that offers a flexible run-time approach. The drawing canvas background, nodes, edges, connectors, and labels each can have rich attributed graphical decorations. Customer applications can provide graphical drawings with "level of detail" support, enabling the end user to expose additional graphical detail as zooming thresholds are passed.

The drawing canvas now supports new hover, select, and highlight metaphors. New precise shape clipping improves drawing resolution.

Also, for large drawings with thousands of nodes, layout performance is markedly improved.

Additionally, a timeline view shows events in chronological order, for use in link analysis applications. A new path trace view supports network management applications. New blinking graphical decorations support network monitoring applications.

This release supports Eclipse SWT, and offers integration with Objectivity InfiniteGraph and Google Earth.

Date	May 22, 2008
Status	General

Overview

This release introduces Tom Sawyer Perspectives, Java Edition, a next generation product that enables you to develop strategic corporate applications that reveal patterns, relationships, and dependencies in your data in an unprecedented way. Built on top of Tom Sawyer's reliable graph visualization and layout component products, Tom Sawyer Perspectives utilizes graphical application design methods to help you construct applications in a fraction of the time usually required.

Tom Sawyer Perspectives provides an intuitive yet powerful graphical environment to configure round-trip data integration and create simultaneous and synchronized, rule-driven views of data. The Tom Sawyer Perspectives Project Designer is used to configure applications to automatically connect to data sources including databases, Microsoft Excel spreadsheets, plain text files, and XML files. The Project Designer also displays numerous simultaneous views of data from different perspectives including drawings, inspectors, trees, and tables. Users may also commit edits back to the data source through the different views. As a result, time-consuming, manual programming efforts are drastically minimized.

Tom Sawyer Perspectives is designed for data analysts, architecture teams, and IT and IS organizations.

New

• Microsoft Excel, JDBC-compliant database, text, and XML data integrators that link directly to your data sources
• Graph drawing, tree, table, and inspector views to view your data from different perspectives
• Filters to define the part of your model to use by the integrators and views
• The Designer, a graphical development tool to define the schema, add integrators, views, and filters
