Create, review, and restyle data visualizations using Edward Tufte principles: high data-ink ratio, direct labels, range-frame axes, small multiples, accessible color, responsive charts, and honest comparisons. Triggers on: "create a chart", "style this chart", "review this graph", "Tufte chart", "data visualization", "Recharts", "Plotly", "matplotlib", "Chart.js", "ECharts", "D3". Use when generating or critiquing charts, dashboards, sparklines, and data tables.
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
# Chart Clarity Create and critique charts that make quantitative comparisons obvious without decorative chartjunk. This skill adapts Caylent's MIT-licensed `tufte-data-viz` skill into armory under the broader `chart-clarity` name. It applies Edward Tufte's core data visualization principles and adds screen-first requirements for accessibility, responsiveness, dark mode, progressive disclosure, and human-readable numbers. Use this skill whenever the user asks for a chart, graph, plot, dashboard visualization, sparkline, slopegraph, data table, or visualization review. It covers Recharts, ECharts, Chart.js, matplotlib, Plotly, seaborn, D3.js, SVG, and HTML. ## When to Use | User need | Use `chart-clarity` | Use instead | |---|---:|---| | Generate chart code in Recharts, Plotly, matplotlib, Chart.js, ECharts, D3, SVG, or HTML | Yes | — | | Review an existing chart for misleading design, clutter, accessibility, or readability | Yes | — | | Restyle dashboard charts while keeping the dashboard structure unchanged | Yes | `ux-expert` for broader dashboard UX | | Build a static infographic or rich HTML artifact around charts | No | `static-web-artifacts-builder` | …

How to install
mdr add mathews-tom/armory/chart-clarity@sha256:6673d21d33cffe13The line at the top of this page pins the label v1.0.0, 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.
