Open Source Linux Charting Libraries

LombokCharts A zero-dependency charting library for the browser. It pairs a small grammar-of-graphics core (Data → Scale → Mark) with pluggable Canvas and SVG renderers, LTTB decimation, and a real-time streaming layer — so the same API draws a five-point bar chart or a five-million-point line without changing shape.

Neiki's Charts is a lightweight SVG chart library built as a native Web Component. Drop a single script tag into any HTML page and get four chart types — Line, Bar, Pie, and Scatter — with no build step, no framework, and zero dependencies. CSS is bundled automatically, so one file is all you need. The component uses Shadow DOM for style encapsulation and fits cleanly into any project without CSS conflicts. Charts are fully responsive, support light and dark themes with automatic prefers-color-scheme detection, and expose a simple JS API for data and options. Tooltips, legends, animations, and grid lines are all controlled through standard HTML attributes. All rendering is pure SVG — no Canvas — making charts scalable, printable, and inspectable in DevTools. Accessibility is built in with proper ARIA roles, keyboard-navigable legends, and full prefers-reduced-motion support.
