charting SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
charting from oaustegard/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add oaustegard/claude-skills/charting@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Select the right Python charting library (seaborn, matplotlib, graphviz) and produce publication-quality static visualizations. Use when creating charts, plots, graphs, diagrams, heatmaps, visualizations from data, or when choosing between matplotlib/seaborn/graphviz. Also triggers for network diagrams, flowcharts, dependency trees, state machines, and entity-relationship diagrams. For interactive browser-rendered charts or uploaded data exploration, defer to charting-vega-lite instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Charting: Python Static Visualizations Select the optimal Python charting library and produce clean, publication-quality output. ## Library Selection Framework Choose the library based on what the visualization represents, not habit. ### Seaborn — DEFAULT for statistical/analytical charts Seaborn wraps matplotlib with better defaults, tighter pandas integration, and fewer lines of code. Reach for seaborn first when the data lives in a DataFrame and the goal is analytical. **Use for:** distributions (histograms, KDEs, violin plots, ECDFs), categorical comparisons (box plots, swarm plots, strip plots, bar plots), correlation (heatmaps, pair plots, regression plots), grouped/faceted views (`FacetGrid`, `catplot`, `relplot`). **Why:** Automatic axis labeling from column names, coherent color palettes, built-in aggregation with confidence intervals, and `hue`/`col`/`row` faceting with minimal code. **Practical rule:** If the code would call `plt.bar()`, `plt.hist()`, `plt.scatter()`, or build a heatmap with `plt.imshow()` — use the seaborn equivalent instead. It will look better with less effort. ### Matplotlib — fine-grained control and non-standard layouts …

How to install
mdr add oaustegard/claude-skills/charting@sha256:11d08da3e3be99a0The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
