Ideate and critique data visualizations using Edward Tufte's principles, and map them onto the PMX Canvas json-render chart catalog (graph / json-render nodes). Use this skill when: (1) Designing or critiquing a canvas graph/json-render chart (2) Choosing a chart type, color encoding (colorBy), or primitive (Sparkline, DotPlot, BulletChart, Slopegraph) (3) Reviewing a board's dashboards/charts for graphical integrity and data-ink (4) Deciding between a single-series bar, small multiples, or…
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
# Tufte Visualization Ideation (PMX Canvas) Apply Edward Tufte's principles to design clear, honest, high-density data visualizations, then realize them with PMX Canvas `graph` / `json-render` nodes. Color must encode data, not decorate. ## Workflow ### For new visualizations: 1. **Clarify the data story** - What comparisons matter? - What's the key insight to communicate? - Who's the audience? 2. **Select approach** using Tufte principles: - High comparison need → Small multiples (several small `graph` nodes, shared scale) - Dense data → Consider data tables (`json-render` Table), sparklines (`Sparkline`) - Time-series → Line charts with minimal grid - Part-to-whole → Avoid pie charts; prefer bar/table - Ranked single metric across categories → DotPlot over a bar forest 3. **Design with data-ink in mind** - Start minimal, add only what's necessary - Every element must earn its ink - Default to a single accent; use the full palette only when color *encodes* a variable 4. **Apply the eraser test before shipping** - For every element (label, tick, gridline, border, annotation): can it be erased without losing …

How to install
mdr add pskoett/pmx-canvas/tufte-viz@sha256:722e402d534994d5The line at the top of this page pins the label git:20260707.f60c5e3, 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.
