What problem does it solve? Scientific figures often fail journal submission or mislead readers because of dishonest encodings, inaccessible color choices, wrong physical dimensions, or unverified publisher rules. This Skill guides the design, export, and audit of truthful, accessible figures while preserving raw data and provenance. ## Core Features & Use Cases - Honest figure design: Enforces integrity guardrails for baselines, uncertainty, missing data, binning, normalization, and dual axes before any plotting code is written. - Deterministic CLI tooling: Bundled network-free scripts inspect raster/SVG/PDF/EPS metadata, audit palette contrast against WCAG thresholds, plan publisher exports from dated profiles, and export Matplotlib figures atomically with provenance manifests. - Accessibility and color review: Provides Okabe-Ito and Paul Tol palettes, WCAG 2.2 contrast checks, grayscale screening, and redundant-encoding guidance. - Use Case: A researcher preparing a Nature submission uses the export planner to check width and DPI rules, builds a multi-panel Matplotlib figure with a scoped style, exports PDF and PNG with a provenance manifest, then screens the delivered file's dimensions and fonts before upload. ## Quick Start Ask the assistant to create a publication-ready multi-panel figure from your data using the scientific-visualization workflow and then audit the exported file's dimensions, DPI, and palette contrast.
