data-visualization

data-visualization is a skill for Claude Code from aneja5/forge-skills. It costs 39 tokens per session (1,652 once invoked), scanned A, original, MIT.

A set of rules for presenting data in dashboards, charts, and reports. It covers chart choices, colors, axes, responsive behavior, empty states, and loading animations.

In plain words
What is it for?
Use it to choose chart types, standardize data colors and tooltips, make charts responsive, and define how empty or loading states appear.
Why use it?
It prevents charts in the same product from using inconsistent designs or misleading visual choices. Shared rules also help dashboards work across screen sizes.

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

data-visualization 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 2mo 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.

Data Visualization

Overview

Pin down chart-type selection rules, data color encoding, axis conventions, responsive behavior, empty states, and load animations before charts proliferate. Output is .forge/data-visualization.md. Reads design-system (color palette, typography) and component-library (chart components). Referenced by every dashboard, report, and analytics surface.

When to Use

  • A dashboard or analytics surface is being built and no chart conventions exist
  • Charts across the product use 8 different color palettes and 3 different tooltip styles
  • A new chart type is being added and the team needs a rule for when to use it
  • Data colors don't track design tokens (raw #3B82F6 inside chart code)
  • A report needs to work on mobile and the existing charts don't respond

When NOT to Use

  • A single one-off chart on a marketing page — use the design system colors and move on
  • A product with no data surfaces (auth, settings, content)
  • A backend-only service

Common Rationalizations

Thought Reality
"Just use whatever chart looks good" Mismatched chart types across a dashboard look like three different products stitched together.
"We'll standardize later" By then you have 8 charts with 8 different palettes and 3 tooltip styles.
"Pie charts are fine" Humans can't accurately compare angles. Donuts with center metrics beat pies; horizontal bars beat both for comparison.
"We don't need empty states for charts" A blank chart area makes users think the product is broken.
"Hover tooltips work everywhere" Hover doesn't exist on touch. Every tooltip needs a tap path.

Red Flags

  • Pie chart used for comparison (use horizontal bar)
  • Color as the only differentiator (no patterns/labels/icons for accessibility)
  • Y-axis not starting at 0 (misleading without a "delta" framing)
  • Inconsistent date formats across charts (MMM DD here, MM/DD/YY there)
  • Chart with no empty state — just a blank rectangle
  • Tooltip that only works on hover (unusable on touch)
  • More than 5 distinct colors in one chart

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.
