# 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.

Read `.claude/skills/data-forms/SKILL.md` and execute it exactly as written — that file is the authoritative
playbook. Then follow `.agents/rules/cog.md`.

Antigravity substitution: where the playbook delegates to a `.claude/agents/<name>`
worker, invoke `.agents/agents/<name>.md` via `invoke_subagent` instead.
