PREFERRED chart-creation path. Send a structured Builder spec (chart_type + x_col + y_col[s] + optional group_by, palette, axis overrides, annotations) and Autario builds the chart with the same templates the Builder UI uses. Brand attribution (publisher source + autario.com) is applied automatically and cannot be overridden. Insight must cite numbers verifiable against the data | hallucinated numbers return 422 with the available anchor list. For advanced use cases the Builder cannot express, fall back to publish_chart with a freeform plotly_spec. Call chart_instructions() first if unsure of the spec shape.
