dataviz

dataviz is a command for Claude Code from aneja5/forge-skills. It costs 11 tokens per session (215 once invoked), scanned A, original, MIT.

A chart-design guide for deciding how data should be shown, colored, labeled, and adapted to different screen sizes.

In plain words
What is it for?
It helps define rules for trend lines, part-to-whole charts, comparisons, distributions, axes, labels, colors, responsive layouts, and chart empty states.
Why use it?
It removes guesswork and inconsistent chart choices. It also covers empty data, reduced motion, and touch interactions such as tap tooltips.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dataviz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Invoke the forge-skills:data-visualization skill.

Read .forge/design-system.md (colors + typography) and .forge/component-library.md (chart components). Define chart-type selection rules as a decision tree (line for trends, donut for part-of-whole, horizontal bar for comparison, histogram for distribution, etc. — no ad-hoc choices). Define data color encoding from design-system semantic tokens — never raw hex. Set axis + label conventions (Y starts at 0, units always shown, consistent date format). Define responsive behavior at each breakpoint and tap-tooltip paths (no hover-only). Empty states with context. Animation per references/motion-system.md, respecting prefers-reduced-motion. Document domain-specific patterns if the product is data-heavy.

Reads: .forge/design-system.md + .forge/component-library.md Produces: .forge/data-visualization.md Next: build charts during /build; run /polish to verify every chart has an empty state and tap-tooltip path.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
