This new version brings extensive new style support with a new flexible group node style, a new rectangular node style, and new arrow-shaped node style and edge style classes. There is also new support for background shapes for labels which includes shape-defined text wrapping out-of-the-box.
Included with this new version are new layout algorithms like the Cactus group layout that provides an alternative representation of hierarchically nested graphs, and the new Compact Disk layout algorithm that arranges a graph densely packed within a circular area. The Radial and Circular layout algorithms feature new support for curved edge routing as well as integrated ray-like node labeling, which enables more natural visualizations. The Radial layout also has new support for a dendrogram-like style now, and the Hierarchical layout style comes with new support for tabular group nodes with tightly stacked nodes inside to create database table representations.
