"""Create the standalone dataset-wide UpSet diagram for I-BADAS.
This script is self-contained. It does not import plot_difficulty.py and does
not require M3DM or STFPM score files. It reads one or more COCO annotation
files, extracts the retained anomaly classes for every image, selects the most
frequent exact class combinations, and writes:
01_upset_dataset_wide.pdf
01_upset_dataset_wide.png
01_upset_dataset_wide_values.csv
Category selection
------------------
- Exclude `box` and `permanent_mortise` by name.
- Retain `nuisance_dent`, even if its supercategory is `box`.
- Retain every other category whose supercategory is not `box`.
Combination selection
---------------------
The main selection contains the `--top-n` most frequent exact combinations
with at least `--min-count` images. Unless `--no-ensure-all-types` is supplied,
the most frequent combination containing each otherwise-missing anomaly class
is appended. The final combinations are sorted by descending image count.
Example
-------
python plot_upset_dataset_wide.py \
--coco test \
--top-n 20 \
--min-count 5 \
--out checkpoint_data/upset_figures
