By default, when the diagram content exceeds the viewport, the diagram scrollbar appears. To remove scrollbar, please use fitToPage method in the created event which triggers when diagram is created. Please refer to a sample below for your reference. Still if you face any problems, please elaborate your exact scenario with screenshot or video.
