"""Thin wrapper around tools/hanoi_pipeline/scripts/materialize_per_frame_graphs.py.

Kept in examples/ so `python examples/04_materialize_per_frame.py` works
side-by-side with the other example entry points.

Usage (from the dataset repo root, after `hf download`):

    python examples/04_materialize_per_frame.py \\
        hanoi/session_hanoi_0415_190808/episode_00 \\
        --out ./per_frame_graphs \\
        --variant with_robot_state \\
        --also-json
