Use when creating, revising, or reviewing explanatory data charts for a blog, report, paper, slide, newsletter, or social post. Includes matplotlib, seaborn, pandas .plot, ggplot2, Plotly, Altair/Vega-Lite, D3, and PNG/SVG charts. Also use for "critique this chart", "why does this plot look bad", or "make this figure better" with a chart image. Not for unrelated coding, software architecture diagrams, or non-data illustrations.
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
# evident-charts
Charts that make one point a reader gets at a glance. `<skill-dir>` is this skill's folder: `${CLAUDE_SKILL_DIR}` where the host fills it in, else the folder holding this SKILL.md (in claude.ai chat, its copy in the sandbox), never the working directory. Run scripts by absolute path with the project's Python.
Critique, review, or a chart image with a question: follow `references/critique.md`; otherwise the workflow below.
## Host and user instructions
- User instructions and host requirements take precedence over this skill, including its evidence rules. Preserve an explicit override, explain the consequence briefly, and report the rule deviation and any failed check; do not silently replace the requested chart.
- Use only available, permitted tools. Python 3.10+ runs the checks; matplotlib checks also need matplotlib and numpy. Palette and SVG scripts use the standard library; SVG layout checks need Chrome/Chromium. Optional helpers or exports may need their own libraries.

How to install
mdr add rhiever/evident-charts/evident-charts@sha256:294e4f568527a17cThe line at the top of this page pins the label v0.2.4, 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.
