Is there a simple way to reverse a link direction between two nodes on a specific nodetype?
Logically, swap the “fromNode” and the “toNode” on the Link, or swap the “from” and the “to” properties on the link data (if you are using a GraphLinksModel).
Or you can change the appearance by changing the arrowhead – instead of setting Shape.toArrow, set Shape.fromArrow (or vice-versa). Note that that does not change the direction of the link, for situations where the direction matters, such as the tree-traversal properties and methods on the Node class.
