Data Charts Visualization

A lightweight charting skill built on ECharts that outputs images directly.

Why This Skill

• Rich chart support: line, bar, pie, donut, rose, gauge, area, dual-axis, scatter, bubble, radar, and funnel.
• Lightweight runtime: render static images without Chromium, Playwright, or browser automation.
• Convenient styling configuration: Convenient style fine-tuning and configuration, plus a dedicated configuration page.
• Agent-friendly contract: keep business data in data, reusable style rules in config, and one-off render choices in variant.

Role

This is the default charting skill for OpenClaw-like agents.

Use it whenever:

• the user explicitly asks for a chart, graph, plot, dashboard, report visual, or report graphic
• the user wants structured data such as CSV, JSON, tables, metrics, or SQL results turned into visual output
• the input already uses charting terms, ECharts-like fragments, or BI-style semantics
