Source Code Demo Applications

Try out the yFiles online demos that showcase the visualization and interaction capabilities of the yFiles family of diagramming software libraries. See the versatility of the yFiles family and the possibilities that yFiles WPF can bring to your own applications!

Graph Editor

The Graph Editor demo application is a fully-featured showcase of the visualization and automatic layout capabilities of yFiles WPF:
  • Add, delete, move, and label nodes and edges to create a graph
  • Interact using zoom and pan, undo/redo, copy/paste, and more
  • Apply graph layout algorithms
  • Load, save, and print graphs, and export graphs to images

Graph Viewer

The Graph Viewer demo application demonstrates user interaction possibilities such as zooming, panning, overview, and toggling additional node information.

Organization Chart

The Organization Chart demo application shows how to create an interactive organization chart with data loaded from XML.

Business Process Models

The Business Process Diagram demo application is an editor for business process diagrams that shows how to:
  • use built-in features such as grouping, swimlanes, and drag-and-drop
  • customize the look and feel of nodes, edges, and arrows
  • customize edge creation, layout calculation, and input modes
  • associate custom data objects with graph items

Collapsible Tree

The Collapsible Tree demo application loads a tree with many nodes, whose branches can be expanded and collapsed. 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 WPF. Group nodes can be collapsed or expanded. Whenever group nodes are expanded or collapsed, a new incremental layout is calculated and the graph is redrawn.

Control Styles

The Control Styles demo application shows how to conveniently define the visual appearance of nodes, edges, and labels using XAML.

This enables your graphic designers to interactively skin and style your application using Expression Blend, for example.

Custom Styles

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