Six data-rich events already published by Pollar were re-written by three frontier models under the production writer prompt, modified in two respects: the fixed chart vocabulary (bar, line, pie, timeline) was opened, letting the writer name any visual form the sourced data calls for, and web access was explicitly forbidden. The frontier articles are unedited model outputs; every chart is rendered live from the JSON the writer returned. The production column is the article as published, after the pipeline's usual post-processing. A datapoint audit found zero fabricated numeric chart values in any output; the audit's scope and one erratum are in the experiment paper.
