Nodes and links are not controls but just low-level DrawingVisual objects, a lightweight way to perform drawing. so you can create big diagrams (several thousands of nodes and links).

With Addflow for WPF you will be able to build flowchart-enabled applications like workflow diagrams, database diagrams, communication networks, organizational charts, process flow, state transitions diagrams, telephone call centers, CRM (Customer Relationship Management), expert systems, graph theory, quality control diagrams, etc.

AddFlow allows building a graph interactively and programmatically. The interactive creation of diagrams is mouse-based. It also supports the scrolling of diagrams, the node in-place editing and the use of grids.

Interactively, without adding any code, you can change the position and the size of a node and also its text. You can add segments to a link or remove them. To change the other properties (shape, styles, colors, behaviors, etc) of a node or a link, you have to write some code.

Both Addflow for WPF editions include advanced features like custom drawings, full integration with the WPF environment or Undo/Redo. The professional version offers also a set of graph layout algorithms (Hierarchic, Force-directed, orthogonal, series-parallel, tree, radial).
