Graph Tools Foundation is a framework to build graph editing tools including a graph data model, a UI foundation and graph-to-asset pipeline.

Graph Tools Foundation provides a set of API to help you develop graph editing tools. As such, it has no functionality immediately available to the user; however, if you write a tool that deals with graphs, Graph Tools Foundation can help you reach your goals more quickly while adhering to a set of Unity UI and UX standards.

Graph Tools Foundation is a framework that you can use to build graph editing tools. It is meant to be configurable and extensible. It provides:

• A set of modular user interface elements, such as nodes and edges.
• A set of interfaces that should be implemented by your graph model. Alternatively, you can choose to derive your graph model from a basic graph model included in the package.
• An extensible and adaptable action-response system that defines how the UI interacts with the graph model. Graph Tools Foundation defines a set of basic graph operations for node and edge creation, cut, copy, and paste of elements, node manipulation, etc. All operations support undo and redo.

• Pan and zoom of the work area
• Node snapping (to grid, to other nodes)
• Placemats to group nodes together
• Horizontal and vertical flow
• Portals
• Editable edge paths
• Edge ordering
• Minimap showing an reduced view of the entire graph
• A blackboard, an working area where you can define things for use in the graph
• A node editor, to edit properties of the nodes
