task_charts__population_pyramid__side_gap_extremum_label

Taxonomy

1. Domain: charts
2. Scene id: population_pyramid
3. Source implementation scene: charts/population_pyramid
4. Public task id: task_charts__population_pyramid__side_gap_extremum_label

Implementation

1. Registered class: trace_tasks.tasks.charts.population_pyramid.side_gap_extremum_label.ChartsPopulationPyramidSideGapExtremumLabelTask
2. Prompt lookup domain/scene: charts/population_pyramid
3. Default dataset: enabled

Contract

1. Query ids: largest_side_gap_label, smallest_nonzero_side_gap_label
2. Answer schema: string_label.
3. Annotation schema: bbox
4. Annotation marks one bbox around the paired left/right bars in the answer row.

Program Contract

Program: select_label(arg_extremum(age_group_rows, abs(left_value - right_value), rank)); scene=population_pyramid; scope=side_gap_extremum_label

Candidate set: the visible left/right population bars and age-group labels inside the side_gap_extremum_label objective scope. Operands: prompt-bound labels, categories, series names, thresholds, intervals, references, and encoded chart values, plus the active query id's comparator, direction, target role, or extremum focus when present. Operation: evaluate select_label over the candidate set using the filters, comparisons, aggregations, rankings, projections, or counterfactual edits named in the program expression; generation enforces a unique final answer. Output binding: answer is the unspecified value bound by unspecified. Annotation witnesses: unspecified witnesses bound by see_annotation_contract. The Annotation Contract below defines the prompt-facing witnesses. Query ids: largest_side_gap_label, smallest_nonzero_side_gap_label.
