What does this skill do?

The Matplotlib skill lets an agent generate professional data visualizations from a simple prompt, applying opinionated design templates and palettes automatically and saving publication-ready PDF and PNG files.

It ships nine pre-built chart patterns — from horizontal bars and time series to violin plots, heatmaps, multi-panel grids, and PR/ROC curves — and picks an appropriate type for the request.

Its design philosophy is data-forward: prioritize data visibility, prefer position over color, remove chart junk, and annotate insights rather than just axes.

  • Generates charts from a one-line prompt

  • Includes nine ready-made chart patterns

  • Uses colorblind-accessible cubehelix and ColorBrewer palettes

  • Saves despined, annotation-rich figures as PDF and PNG

How it works

1

Describe the chart

The agent takes a one-line prompt describing the data and the comparison to show.

2

Select a pattern

It picks an appropriate chart type from the nine patterns and applies the matching design template.

3

Apply the design system

It uses colorblind-accessible palettes, despined minimal-ink styling, value labels, and insight annotations.

4

Save the figures

It saves publication-ready output as PDF and PNG to a figures directory.

Best use cases for this skill

  • Quick charts: Turn a one-line prompt into a polished figure.

  • Publication figures: Produce despined, annotation-rich charts for reports.

  • Distribution comparisons: Use violin, heatmap, or multi-panel patterns.

  • Model evaluation: Plot PR and ROC curves for classification results.

Frequently asked questions

What does the Matplotlib skill do?

It generates publication-quality matplotlib and seaborn charts from a one-line prompt — colorblind-accessible, despined, annotation-rich figures saved as PDF and PNG.

When should an agent use it?

Use it whenever you need a clean, publication-ready chart quickly, from category comparisons to time series, distributions, heatmaps, and classification curves.

Is it accessible?

Yes. It uses colorblind-accessible palettes such as cubehelix and ColorBrewer and encodes meaning through multiple channels, not color alone.

What formats does it output?

It saves figures as both PDF and PNG to a figures directory.
