The upcoming yFiles for Java 3.0 is the next-generation yFiles diagramming library for the Java Swing GUI toolkit.

The library contains UI controls for viewing and editing diagrams and our mature layout algorithms for automatically arranging complex graphs and networks at the click of a button.

We plan to release yFiles for Java 3.0 in parallel to the existing yFiles for Java 2.x library in 2015. So, yFiles for Java 2.x will be here to stay!

Evaluate

Powerful Graph Controls

The powerful Java Swing components of yFiles for Java 3.0 enable intuitive interaction with diagrams.

• Easily edit and handle diagrams with simple mouse gestures.
• Enjoy smooth change animations and "magnetic" guide lines for manual element alignment.
• Benefit from out-of-the-box support for zooming and panning, undo/redo, clipboard functionality, image export, and printing.
• Customize interaction capabilities easily to fit your specific needs.

Graph Analysis and Automatic Layout

yFiles for Java 3.0 provides a wide variety of graph analysis algorithms that let you tackle the most challenging analysis tasks easily.

• The suite of automatic layout algorithms includes Hierarchic, Orthogonal, and Circular layout styles to automatically yield clear and concise diagrams from your data.
• Routing algorithms optimize connection lines in existing diagrams.
• Ample configuration possibilities suit even sophisticated layout demands.

Java 8 Support
Full support for Java language level 1.8, including lambda expressions, default methods, streams, and generics.

Flexible, Context-aware Behavior
Easily add new "aspects" to graph elements without the need for subclassing. Modify the behavior of graph elements at runtime by simply changing their look-up to return appropriate new logic.

Vastly Enhanced Event Support
Fine-grained event framework API that provides distinct listeners for each type of event.

Versatile and Even Faster Visualization Component
Scene graph based GraphControl component which features separate visualization layers for graph elements. It manages "view properties" of graph elements, like selection state and focused state.

Business Data Access Made Even Easier
Dedicated 'tag' property on all graph elements for direct storage of your business data.

Shareable Styling
The clean separation of geometry and visualization for graph elements enables shareable visualization styles for graph elements out-of-the-box.

Design Patterns Easily Applicable
Visualization styles and renderers are designed as interface hierarchies, making them well suited for decoration and delegation design patterns.

Customization of Interaction Gestures Made Simple
Easy customization of user interaction gestures through properties and fine-grained events.

Graph Editor

The Graph Editor demo application is a fully-featured showcase of the visualization and automatic layout capabilities of yFiles for Java 3.0:

• Add, delete, move, and label nodes and edges to create a graph
• Interact using zoom and pan, undo/redo, copy/paste, and more
• Apply layout algorithms
• Load and save graphs from GraphML, export graphs to images

Graph Viewer

The Graph Viewer demo application demonstrates user interaction possibilities such as zooming and panning. Graphs from various domains are loaded and enriched with extra information for descriptions and tooltips during the loading process.

Organization Chart

The Organization Chart demo application displays an interactive organization chart with data loaded from XML.

Collapsible Tree

The Collapsible Tree demo application displays a tree-like structure that can be expanded and collapsed interactively. The nodes are rendered with custom icons that indicate their current state. After an expand or collapse operation, the graph is redrawn using a configurable layout algorithm.

Grouped Graph

The Grouped Graph demo application presents the grouping support of yFiles for Java 3.0. Group nodes can be collapsed or expanded. Additionally, when a group node is expanded or collapsed, a new incremental layout is calculated and the graph is redrawn.

Custom Styles

The Custom Styles tutorial shows how to easily change the look and feel of nodes, edges, and labels to create attractive visual representations of graph structures.
