| ## Data Fields |
|
|
| The public viewer layout in `hf_viewer/{train,validation,test}/metadata.jsonl` keeps a slimmer schema: |
|
|
| - `sample_id` |
| - `chart_id` |
| - `chart_type` |
| - `chart_group` |
| - `image_path` |
| - `values` |
| - `n_series` |
| - `n_points` |
| - `difficulty_tier` |
| - `difficulty_components` |
| - `challenge_tags` |
| - `source_kind` |
| - `layout_family` |
| - `split` |
| - `suite_id` |
| - `annotation` |
| - `axis_scale` |
| - `x_labels` |
| - `series_labels` |
| - `candidate_pool` |
| - `table_path` |
| - `program_path` |
| - `object_path` |
|
|
| The canonical audit manifest remains available in `metadata/formal_all18_432.jsonl`. |
