Individual skill
data-forms
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 post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.

# 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.
