data-visualization

data-visualization is a skill for Claude Code, Codex from Dannykkh/skill-olympus. It costs 101 tokens per session (3,173 once invoked), scanned A, original, MIT.

Create effective data visualizations with Python (matplotlib, seaborn, plotly). Use when building charts, choosing the right chart type for a dataset, creating publication-quality figures, or applying accessibility and color theory. 데이터 시각화, 통계 그래프, "이 데이터엔 어떤 차트?", 대시보드 차트 구성 판단, /data-visualization 요청에 사용한다.

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 today.

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 Skill

Chart selection guidance, Python visualization code patterns, design principles, and accessibility considerations for creating effective data visualizations.

Chart Selection Guide

Choose by Data Relationship

What You're Showing Best Chart Alternatives
Trend over time Line chart Area chart (if showing cumulative or composition)
Comparison across categories Vertical bar chart Horizontal bar (many categories), lollipop chart
Ranking Horizontal bar chart Dot plot, slope chart (comparing two periods)
Part-to-whole composition Stacked bar chart Treemap (hierarchical), waffle chart
Composition over time Stacked area chart 100% stacked bar (for proportion focus)
Distribution Histogram Box plot (comparing groups), violin plot, strip plot
Correlation (2 variables) Scatter plot Bubble chart (add 3rd variable as size)
Correlation (many variables) Heatmap (correlation matrix) Pair plot
Geographic patterns Choropleth map Bubble map, hex map
Flow / process Sankey diagram Funnel chart (sequential stages)
Relationship network Network graph Chord diagram
Performance vs. target Bullet chart Gauge (single KPI only)
Multiple KPIs at once Small multiples Dashboard with separate charts

When NOT to Use Certain Charts

  • Pie charts: Avoid unless <6 categories and exact proportions matter less than rough comparison. Humans are bad at comparing angles. Use bar charts instead.
  • 3D charts: Never. They distort perception and add no information.
  • Dual-axis charts: Use cautiously. They can mislead by implying correlation. Clearly label both axes if used.
  • Stacked bar (many categories): Hard to compare middle segments. Use small multiples or grouped bars instead.
  • Donut charts: Slightly better than pie charts but same fundamental issues. Use for single KPI display at most.

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.

data-visualization is a skill published in the GitHub repository Dannykkh/skill-olympus (5 stars, last pushed 2d ago), licensed MIT. It adds 101 tokens to every session and 3,173 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
