chart-image is a Claude Code skill that generates publication-quality PNG chart images from data without a browser or native build tools. It supports eight chart types — line, bar, area, point, pie, donut, candlestick (OHLC), and heatmap — including multi-series and stacked variants. Internally it uses a Node.js script built on Vega-Lite and Sharp with prebuilt binaries, keeping total dependencies around 15 MB compared to 400 MB+ for Puppeteer-based solutions, with chart generation completing in under 500 ms. The skill is designed for headless server environments such as Fly.io, VPS, and Docker deployments where charts need to be embedded in reports, dashboards, or monitoring alerts; additional options cover dark mode, SVG export, dual Y-axis volume overlays, sparklines, and percent-change annotations.
