Data Visualizer
Build charts, dashboards, and interactive data visualizations using modern libraries. Covers Recharts (React), Chart.js (framework-agnostic), and D3.js (custom/advanced).
Library Selection
| Library | Best For | React | Custom | Bundle (gzip) |
|---|---|---|---|---|
| Recharts | Quick React charts, standard types | Native | Limited | ~139KB |
| Chart.js | Framework-agnostic, simple API | Wrapper | Moderate | ~68KB (tree-shakeable) |
| D3.js | Custom visualizations, full control | Manual | Full | ~13-30KB per module |
Chart Type Selection
| Chart | Best For | Avoid When |
|---|---|---|
| Line | Trends over time, continuous data | Categorical data |
| Bar | Comparing categories, rankings | Continuous data |
| Pie/Donut | Part-to-whole (max 5-7 slices) | >7 categories, precise comparison |
| Area | Volume over time, stacked categories | Too many overlapping series |
| Scatter | Correlation, outliers, distribution | Time series |
| Heatmap | Intensity across two dimensions | Simple comparisons |
Dashboard Patterns
| Pattern | Use Case | Key Feature |
|---|---|---|
| KPI Dashboard | Executive metrics | Trend indicators, card grid |
| Real-Time | Live monitoring | SSE/WebSocket, animation disabled |
| Interactive Filters | Exploratory analysis | Period/region selects, drill-down |
| Drill-Down | Hierarchical data | Click to zoom (year → month → day) |
Responsive Design
| Approach | Implementation |
|---|---|
| Container-based sizing | <ResponsiveContainer width="100%" height={300}> |
| Aspect ratio mode | <ResponsiveContainer width="100%" aspect={2}> |
| Mobile-aware | Reduce strokeWidth, height on small screens |
| Label simplification | Fewer axis labels on mobile |
Common Mistakes
| Mistake | Fix |
|---|---|
| Fixed width/height | Use ResponsiveContainer |
| Animation on real-time data | Set isAnimationActive={false} |
| Too many pie slices | Max 5-7 slices, group rest as "Other" |
| Non-accessible colors | Use WCAG AA compliant, colorblind-safe palette |
| Loading entire chart library | Lazy load with dynamic imports |
| No data formatting | Use Intl.NumberFormat for currency/percent |

How to use this skill
Install data-visualizer by running npx skills add oakoss/agent-skills --skill data-visualizer in your project directory. Run the install command above in your project directory. The skill file will be downloaded from GitHub and placed in your project.
No configuration needed. Your AI agent (Claude Code, Cursor, Windsurf, etc.) automatically detects installed skills and uses them as context when generating code.
The skill enhances your agent's understanding of data-visualizer, helping it follow established patterns, avoid common mistakes, and produce production-ready output.
What you get
Skills are plain-text instruction files — not executable code. They encode expert knowledge about frameworks, languages, or tools that your AI agent reads to improve its output. This means zero runtime overhead, no dependency conflicts, and full transparency: you can read and review every instruction before installing.
Compatibility
This skill works with any AI coding agent that supports the skills.sh format, including Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider, and other tools that read project-level context files. Skills are framework-agnostic at the transport level — the content inside determines which language or framework it applies to.
