Synchronize all the changes with visual appearance. You may call this method after all your data is updated (it means after you called updateData and PlayTransition because PlayTransition only says that transition should start playing and does not wait till it plays completely) to ensure that the visual appearance will be updated as soon as possible. You may call this method on the big dataset to reduce lag between your updateData call and actual updating.
