npx skills add antvis/chart-visualization-skills- 📊 chart-visualization: A comprehensive chart generation skill powered by AntV that provides 26+ chart types for intelligent data visualization.
Chart Visualization intelligently selects the most appropriate chart type from 26+ available options, extracts parameters based on detailed specifications, and generates high-quality chart images. It covers time series, comparisons, part-to-whole, relationships, geographic, hierarchical, statistical, and specialized visualizations.
- 🎨 infographic-creator: Create beautiful infographics based on given text content. Use when users request to create infographics.
Infographic Creator uses AntV Infographic to transform data, information, and knowledge into a perceptible visual language. It combines visual design with data visualization, providing 50+ templates including lists, sequences, hierarchies, comparisons, relations, and charts. It compresses complex information with intuitive symbols to help audiences quickly understand and remember key points.
- 🖼️ icon-retrieval: Search and retrieve icon SVG strings from icon library. Returns up to 5 matching icons by default (customizable).
Icon Search helps users find appropriate icons for various use cases including infographics, web development, design, and more. Search by keywords to discover available icons and retrieve their SVG strings directly. Each search returns up to 5 matching icons by default (customizable via topK parameter) with their URLs and complete SVG content.
- 📝 narrative-text-visualization: Generate structured narrative text visualizations from data using T8 Syntax.
Narrative Text Visualization (T8) transforms unstructured data into semantically rich narrative reports using T8 Syntax - a declarative Markdown-like language for creating data narratives with entity annotations. It's LLM-friendly and framework-agnostic, working seamlessly with HTML, React, and Vue. Perfect for creating data analysis reports, summaries, and insights documents with entities like metrics, values, trends, and dimensions properly labeled. Features include built-in mini charts, standardized styling, and professional formatting. Supports authentic data sources and provides lightweight, technology-agnostic rendering.
- 📋 antv-s2-expert: S2 multi-dimensional cross-analysis table development assistant. Use when users need help with S2 pivot tables, table sheets, or any @antv/s2 related development.
AntV S2 Expert helps users develop with the S2 multi-dimensional cross-analysis table engine. It provides comprehensive guidance on @antv/s2 core engine, @antv/s2-react and @antv/s2-vue framework bindings, @antv/s2-react-components advanced analysis components, and @antv/s2-ssr server-side rendering. Covers pivot tables, table sheets, custom cells, theming, events, interactions, sorting, totals, tooltips, frozen rows/columns, icons, pagination, and more.
- 📈 antv-g2-chart: G2 v5 chart code generator. Use when users need to generate G2 charts — bar charts, line charts, pie charts, scatter plots, area charts, heatmaps, and any statistical data visualization with the G2 library.
AntV G2 Chart generates accurate, runnable G2 v5 code following Spec Mode best practices. It covers 30+ chart types (interval, line, area, point, rect, cell, treemap, sankey, chord, wordCloud, gauge, and more), data transforms (stackY, dodgeX, binX, fold, etc.), coordinate systems (cartesian, polar, theta, radial), scales, interactions (brush, slider, legend filter), components (axis, legend, tooltip, annotation), and multi-view compositions. Built-in guard rails prevent common v4→v5 migration pitfalls such as using deprecated chain APIs, invalid palette names, or referencing d3 in user code.
Evaluation Results
Harness Engineering approach has been rigorously tested against 174 chart generation test cases, demonstrating significant improvements over baseline methods:
| Model | Success Rate | Improvement |
|---|---|---|
| qwen3-coder-480b-a35b-instruct | 98.2% | +18.2% |
| Kimi-K2.5 | 97.7% | +17.7% |
| GLM-5.1 | 93.6% | +13.6% |
| DeepSeek-V3.2 | 87.3% | +7.3% |
| Context7 Baseline | 80% | baseline |
The results show that Harness Engineering enables LLMs to achieve near-production-ready accuracy (up to 98.2%), significantly outperforming the Context7 baseline approach.
