   With AngularJS 1.5 <svg> <g ng-if="ctrl.nodes.length && ctrl.links.length"> <line ng-repeat="link

   in ctrl.links" ng-attr-x1="{{link.source.x}}" ng-attr-y1="{{link.source.y}}" ng-attr-x2="{{link.target.x}}" ng-attr-y2="{{link.target.y}}" ></line> <circle ng-repeat="node in ctrl.nodes" r="5" title="node.id" ng-attr-cx="{{node.x}}" ng-attr-cy="{{node.y}}" ng-attr-fill="{{ctrl.hsl(node)}}" ng-click="ctrl.onClick(node)" ng-class="{selected: node.id===ctrl.selectedNode.id}" ></circle> </g> </svg> force.on('tick', () => { this.$scope.$digest(); // ࣗ෼ͰDigestϧʔϓճ͢ඞཁ͋Γ });

   With Angular 2 <svg> <g *ngIf="nodes?.length && links?.length"> <line *ngFor="#link

   of links" [attr.x1]="link.source.x" [attr.y1]="link.source.y" [attr.x2]="link.target.x" [attr.y2]="link.target.y" ></line> <circle *ngFor="#node of nodes" r="5" [attr.title]="node?.id" [attr.cx]="node.x" [attr.cy]="node.y" [attr.fill]="hsl(node)" (click)="onClick(node)" [class.selected]="node?.id===selectedNode?.id" ></circle> </g> </svg> force.on('tick', () => { // উखʹzone.js͕ಈ͘ͷͰԿ΋͢Δඞཁͳ͠ });
