What Data Forms does

Data Forms helps you choose a chart or diagram form that makes a dataset readable in seconds. It covers common survey, benchmark, metric, and research cases, plus labeling and encoding rules that make the result clear.

Data Forms is cataloged under Data on DirSkills. Data Forms comes from a repository tagged agent-loop, agent-plugins, agent-skills, agentic and ai-agents.

Excerpt

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.
