What problem does it solve? Producing journal-ready scientific figures requires juggling plotting code, journal-specific formatting rules, data integrity, and pre-submission QA; this Skill turns raw data, legends, or manuscript claims into compliant multi-panel figures with reproducible scripts and audit records. ## Core Features & Use Cases - Publication-grade plotting in Python or R: Generates matplotlib/seaborn or ggplot2/patchwork/ComplexHeatmap scripts with a persisted backend preference, editable SVG text, and SVG/PDF/TIFF export at 300 dpi. - Journal contract enforcement: Applies flagship Nature and Nature Machine Intelligence rules for main displays, Extended Data, legend word limits, resolution, and source-data traceability. - Automated QA pipeline: Runs static validation on plotting source, audits exported PDFs for sub-5pt glyph sizes, and enforces panel-by-panel visual review before delivery. - AI schematic route: Optionally drafts graphical abstracts and mechanism diagrams via the OpenRouter GPT Image 2 API with policy gating, disclosure, and provenance tracking. - Use Case: A researcher provides a CSV of experimental results and asks for a Nature-style multi-panel figure; the Skill writes the Python script, exports editable SVG/PDF, maps source data, and delivers a pre-submission QA record. ## Quick Start Ask the assistant to turn your dataset into a Nature-style multi-panel figure, stating whether you prefer Python or R and the target journal.
