Links

You can have different types of links

You can use the render-link event to change the link:

 
    family.on('render-link', function(sender, args){
        var cnodeData = family.get(args.cnode.id); 
        var nodeData = family.get(args.node.id);
  
        if (cnodeData.divorced != undefined && nodeData.divorced != undefined &&
          cnodeData.divorced.includes(args.node.id) && nodeData.divorced.includes(args.cnode.id)) {
            console.log(args.html);
            args.html = args.html.replace("path", "path stroke-dasharray='3, 2'");
        }
    });
