What it does
Datavis is an agent skill from foryourhealth111-pixel/Vibe-Skills. Comprehensive data visualization toolkit for creating beautiful, mathematically elegant visualizations with D3.js, Chart.js, and custom SVG. Use when (1) building interactive data visualizations, (2) designing color palettes for charts, (3) choosing scales and visual encodings, (4) creating data pipelines from Census/SEC/Wikipedia APIs, (5) crafting narrative-driven data stories, (6) making perceptually accurate charts, or (7) implementing force-directed networks, timelines, or geographic maps.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/analyze-distribution.py`, `scripts/color-palette.py` and `scripts/d3-scaffold.py`).
It sits in Data & Analytics, covering Data visualization, Theming and dark mode and Data pipelines and ETL. It works with D3.js, Chart.js and Wikipedia. The repository describes itself as: Intelligent Skill routing and workflow orchestration for AI agents — +21.12 pp reward, −29.6% tokens on SkillsBench with DeepSeekV4Flash-VE. The licence is Apache-2.0.
When your agent uses it
- Building interactive data visualizations
- Designing color palettes for charts
- Choosing scales and visual encodings
- Creating data pipelines from Census/SEC/Wikipedia APIs
Example prompts
- “/datavis”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit ddcaa2a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Datavis loads about 1.1k tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 251 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Data Visualization Skill
Create beautiful, mathematically elegant, emotionally resonant data visualizations.
Philosophy: "Life is Beautiful"
Every visualization should:
- Reveal truth through data
- Evoke wonder through design
- Respect the viewer through accessibility
- Honor complexity through elegant simplification
Core Capabilities
1. Visual Encoding
Scale Selection:
| Scale | Use When | Example |
|---|---|---|
| Linear | Evenly distributed data | Temperature |
| Log | Multiple orders of magnitude | Population (100 to 1B) |
| Sqrt | Encoding area (circles) | Bubble chart radius |
| Time | Temporal data | Dates |
Perceptual Honesty - Area scales with square of radius, so use sqrt:
// WRONG: Linear radius exaggerates large values
const badScale = d3.scaleLinear().domain([0, max]).range([0, maxRadius]);
// RIGHT: Sqrt maintains perceptual accuracy
const goodScale = d3.scaleSqrt().domain([0, max]).range([0, maxRadius]);2. Color Design
Palette Types:
- Categorical - Distinct hues for nominal data (max 8)
- Sequential - Single hue gradient for ordered data
- Diverging - Two hues meeting at meaningful midpoint
Colorblind-Safe Palette (8 colors):
const colorblindSafe = [
'#332288', '#117733', '#44AA99', '#88CCEE',
'#DDCC77', '#CC6677', '#AA4499', '#882255'
];Always use redundant encoding - don't rely on color alone:
node.attr('fill', d => colorScale(d.category))
.attr('d', d => symbolScale(d.category)); // Shape too!3. D3.js Patterns
Force Simulation:
const simulation = d3.forceSimulation(nodes)
.force('charge', d3.forceManyBody().strength(-300))
.force('link', d3.forceLink(links).id(d => d.id))
.force('center', d3.forceCenter(width/2, height/2))
.force('collision', d3.forceCollide().radius(d => d.r + 2));Responsive SVG:
const svg = d3.select('#chart')
.append('svg')
.attr('viewBox', `0 0 ${width} ${height}`)
.attr('preserveAspectRatio', 'xMidYMid meet');Touch-Friendly (44x44px minimum):
node.append('circle')
.attr('class', 'hit-area')
.attr('r', Math.max(actualRadius, 22))
.attr('fill', 'transparent');4. Narrative Structure
Three Acts:
- Invitation - What draws viewer in? Why should they care?
- Discovery - What patterns emerge? What surprises?
- Reflection - What should they feel/understand/do?
Progressive Disclosure:
Level 1: Overview → Level 2: Exploration → Level 3: Detail → Level 4: Context5. Data Pipeline

scripts/d3-scaffold.py my-viz --type choroplethAnti-Patterns to Avoid
- 3D charts (distorts perception)
- Pie charts with >6 categories
- Dual y-axes
- Rainbow color scales (perceptually uneven)
- Truncated y-axes without disclosure
- Animation without purpose
Quality Checklist
- Scale choice justified for data distribution
- Color palette is colorblind-safe
- Minimum 44x44px touch targets
- Clear entry point for viewer
- Sources documented
- Responsive on mobile

Can I use Datavis in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add foryourhealth111-pixel/Vibe-Skills --skill datavis -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/datavis, .gemini/skills/datavis, .github/skills/datavis and .opencode/skills/datavis in your project.
What does Datavis need to run?
Going by SKILL.md and its folder, Datavis needs Python for the scripts in its folder. Our summary lists: Python 3.
Does Datavis access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Datavis safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Datavis use?
Datavis is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Datavis use?
About 1.1k tokens (SKILL.md is roughly 4.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
