          var line = new kendo.drawing.Path()
          .moveTo(targetPoint.x, targetPoint.y)
          .lineTo(targetPoint.x, targetPoint.y - 10);
          var circle = new kendo.drawing.Circle(new kendo.geometry.Circle([targetPoint.x, targetPoint.y - 30], 20), {
            fill: {

          var bbox = text.bbox();
          text.position([targetPoint.x - 20 + (40 - bbox.width()) / 2, targetPoint.y - 50 + (40 - bbox.height()) / 2]);
          return new kendo.drawing.Group().append(line, circle, text);
