Copied from the file, not written here

Publication-ready matplotlib figures for Nature/high-impact journals and academic papers. Covers bar charts, grouped bars, heatmaps, line/trend plots, forest plots, microscopy-style image panels, schematic + quantitative composites, radar plots, and multi-panel layouts with Nature-style typography (Arial/sans-serif), restrained color systems, and SVG/PDF export conventions. Use when creating scientific figures that must match Nature publication standards. Do NOT use for interactive dashboards (Plotly, Bokeh) or Illustrator/Figma-first infographic workflows.

Nature Figure Making Skill

A complete guide for producing publication-quality matplotlib figures matching Nature journal standards. Derived from the figures4papers repository (papers published in Nature Machine Intelligence and top ML venues), then extended with direct visual observations from a 2026 Nature sample spanning materials science, genomics, neuroscience, plant biology and clinical studies.

Color policy: prefer unified method families across all panels over maximal hue separation. For dense Nature Machine Intelligence-style figure pages, use the low-saturation NMI pastel family described in references/api.md and reserve green/red mainly for gains, drops, and other directional cues.

Quick-start: Mandatory rcParams

Always apply these at the top of every script:

import matplotlib.pyplot as plt

plt.rcParams['font.family'] = 'sans-serif'
plt.rcParams['font.sans-serif'] = ['Arial']
plt.rcParams['svg.fonttype'] = 'none'          # editable text in SVG/PDF
plt.rcParams['font.size'] = 16                 # 24 for large bar panels
plt.rcParams['axes.spines.right'] = False
plt.rcParams['axes.spines.top'] = False
plt.rcParams['axes.linewidth'] = 2.5           # 3 for big bars, 2 for compact
plt.rcParams['legend.frameon'] = False

Use text.usetex = True only when LaTeX is installed and math-rich labels are required.

Default operating stance

Start by classifying the requested figure into one of four archetypes: quantitative grid, schematic-led composite, image plate + quant, or asymmetric mixed-modality figure.
Prefer one hero panel plus subordinate evidence panels over filling the canvas with equal-sized subplots.
Keep the background white for plots and diagrams; switch to black only for microscopy / volume-rendering image plates.
Prefer direct labels over legends when categories are spatially fixed or the legend would force unnecessary eye travel.
Keep one restrained palette per figure: usually one neutral family, one signal family, and one accent family.
When the user asks for broad Nature style rather than ML/NMI-specific style, read references/nature-2026-observations.md before choosing layout.

When to load this skill

Matplotlib figures for papers, slides, or reports targeting Nature, NeurIPS, ICLR, or similar venues.
Requests involving grouped bars, trend lines, heatmaps, radar plots, multi-panel grids, or PDF/SVG/high-DPI output.
Any mention of "Nature style", "publication figure", "paper figure", or "high-quality scientific plot".

When NOT to load

Plotly, Altair, Bokeh, or other interactive/web-first plotting.
EDA-only plots without a publication target.
Primary workflow is 3D, GIS, or non-matplotlib tooling.
Illustrator / Figma–first layout.
