Tom Sawyer Perspectives, Java Edition

Release 7.2.0

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. Model population, rule execution and expression evaluation, view loading, layout, and rendering are all significantly faster, particularly with large data sets. Further, this release improves product quality and features, and introduces new example applications.
