What problem does it solve? Preparing figures that meet journal submission standards is tedious: wrong DPI, non-colorblind-safe palettes, incorrect column widths, and missing error bars cause desk rejections and revision cycles. This Skill encodes the technical requirements of major journals (Nature, Science, Cell, PLOS, ACS, IEEE) and applies them automatically to matplotlib, seaborn, and plotly figures. ## Core Features & Use Cases - Journal-specific export: Save figures with correct formats, DPI, and dimensions using save_for_journal() and verify compliance with check_figure_size(). - Colorblind-safe palettes: Apply Okabe-Ito, Wong, and Paul Tol palettes via assets/color_palettes.py, plus guidance on perceptually uniform and diverging colormaps. - Publication styling: Pre-configured matplotlib style files and style_presets.py helpers for fonts, sizes, and spine removal matching journal specs. - Use Case: A researcher finishing a Nature manuscript needs a multi-panel figure at 89 mm single-column width with lowercase bold panel labels, 1000 DPI line art, and colorblind-safe colors — the Skill configures the style, validates the size, and exports PDF/EPS in one workflow. ## Quick Start Ask the AI to create a publication-ready multi-panel figure for Nature using colorblind-safe colors and export it as PDF at the correct size and resolution.
