Usage: python plot_chunk_metrics.py [--output-dir output/chunk_metrics]
Dependencies: matplotlib, numpy.
Data are copied exactly from the user's chunk-size measurements.
The two linear y axes display delta_1 on the supplied 93--97 scale and
AbsRel on the supplied 6.5--8.5 scale. The bar display starts at 93;
the tick labels show this nonzero baseline explicitly. No normalization,
smoothing, interpolation, uncertainty bands, or axis breaks are applied.
