Pick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a…
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
# data-forms A repertoire, not a style. Distilled from Lenny's Newsletter data illustrations (2025-2026 survey issues) — what makes those charts work is not the palette, it's the form selection and the encoding discipline. Both are portable to any visual language. For the visual layer, use whatever the destination already has: your product's brand tokens for in-product surfaces, the built-in `dataviz` skill for palette construction and accessibility, your house style for personal sites. This skill decides *what shape the data takes* — the layer above color. ## Start here: the picker | What the data does | Reach for | Form # | |---|---|---| | One question, 3-6 ordered answers | Ordered column · Waffle · Nested bands | 1 · 6 · 7 | | One question, many multi-select answers | Ranked bar · Valence bar | 3 · 4 | | Same metric, two points in time | Paired columns · Slope | 2 · 9 | | Same metric, 3+ points in time | Time-series area · Bump | 13 · 18 | | One metric across 7-10 ordered buckets | Staircase column | 14 | | One metric across many unordered segments | Small multiples · Dot plot | 8 · 17 | | Signed score (-100…+100, net, delta) | Diverging bar | 5 | …

How to install
mdr add huytieu/cog-second-brain/data-forms@sha256:d96b22d059ac3316The line at the top of this page pins the label git:20260807.b852369, 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.
