Tom Sawyer Perspectives, Java Edition

Release 6.2.0

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.
