data-visualizer

data-visualizer is a skill for Claude Code, Codex from daffy0208/ai-dev-standards. It costs 19 tokens per session (4,846 once invoked), scanned A, original, MIT.

A guide for turning data into charts, interactive dashboards, and visual reports. It covers common charts as well as more complex views such as heatmaps and network graphs.

In plain words
What is it for?
Use it to build line, bar, pie, scatter, and other charts; create dashboards with filters and drill-downs; and choose suitable chart libraries and accessible colors.
Why use it?
It helps make patterns, comparisons, and key measurements easier to understand than raw tables or text.

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-visualizer 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 4d 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 Visualizer Skill

I help you build beautiful, interactive data visualizations and dashboards.

What I Do

Chart Creation:

  • Line charts, bar charts, pie charts
  • Area charts, scatter plots, heatmaps
  • Complex visualizations (Sankey, treemaps, network graphs)

Dashboard Building:

  • KPI cards and metrics
  • Real-time data dashboards
  • Interactive filters and drill-downs
  • Responsive layouts

Data Presentation:

  • Data storytelling
  • Color schemes and accessibility
  • Animation and interactions
  • Export capabilities

Library Selection Guide

Recharts (Recommended for React)

Best for:

  • Quick, simple charts
  • React/Next.js projects
  • Standard chart types
  • Responsive design

Example:

import { LineChart, Line, XAxis, YAxis, CartesianGrid, Tooltip, Legend } from 'recharts'

const data = [
  { month: 'Jan', revenue: 4000, expenses: 2400 },
  { month: 'Feb', revenue: 3000, expenses: 1398 },
  { month: 'Mar', revenue: 2000, expenses: 9800 },
]

function RevenueChart() {
  return (
    <LineChart width={600} height={300} data={data}>
      <CartesianGrid strokeDasharray="3 3" />
      <XAxis dataKey="month" />
      <YAxis />
      <Tooltip />
      <Legend />
      <Line type="monotone" dataKey="revenue" stroke="#8884d8" />
      <Line type="monotone" dataKey="expenses" stroke="#82ca9d" />
    </LineChart>
  )
}

Chart.js (Recommended for Vue/Angular)

Best for:

  • Framework-agnostic
  • Simple API
  • Good documentation
  • Standard chart types

Example:

import { Chart } from 'chart.js/auto'

const ctx = document.getElementById('myChart')
const chart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'],
    datasets: [
      {
        label: 'Sales',
        data: [12, 19, 3, 5, 2, 3],
        backgroundColor: 'rgba(54, 162, 235, 0.5)'
      }
    ]
  },
  options: {
    responsive: true,
    plugins: {
      legend: { position: 'top' },
      title: { display: true, text: 'Monthly Sales' }
    }
  }
})

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
