task_charts__radial_sankey__dominant_endpoint_label

Contract

1. Domain: charts
2. Scene id: radial_sankey
3. Task id: task_charts__radial_sankey__dominant_endpoint_label
4. Objective contract: dominant_endpoint_label
5. Supported query_id values: largest_target_for_source, largest_source_for_target

Program Contract

Program: argmax_label(endpoint(flow), value(flow), fixed_opposite_endpoint); scene=radial_sankey; scope=dominant_endpoint_label

Candidate set: the visible radial flow nodes, links, and labels inside the dominant_endpoint_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 argmax_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 string_label value bound by string_label. Annotation witnesses: bbox witnesses bound by see_annotation_contract. Annotation marks the selected source or target endpoint node box. The flow curves, title, panel frame, ring, and unrelated nodes are context unless explicitly referenced by the task. Query ids: largest_target_for_source, largest_source_for_target.
