This sample displays all predefined GoJS arrowheads. Select or hover over a Node or its Link to see the names of the arrowheads on the Link.
Each Link shows two arrowheads. The Link template has a Shape whose Shape.toArrow property is bound to an arrowhead name. A different Shape in the template has its Shape.fromArrow property bound to a different arrowhead name. Each arrowhead has been scaled up to make it more easily visible.
See the definitions of all these arrowheads in the file: Arrowheads.js.
For predefined shape geometries, see the Shapes sample.
