Mohamed, You should do this with "Group Datasets". Group your children nodes together, then apply a Transform filter to the group. You can further group the Transform filters to apply additional rotations to the higher level grouping as you would expect in a scene graph.
This won't be as efficient as applying a transform at every scene graph level in the GPU, for example, but it should provide you some basic scene graph capabilities.
