@graphysdk/viz-engine

The Graphy chart engine. Build a spec and compile it — no DOM, no React.

React apps should start with @graphysdk/react.

Learn more at graphy.dev.

Install

npm install @graphysdk/viz-engine

Usage

import { createSpec, pipe, geom, scale, createCompiler } from '@graphysdk/viz-engine';

const spec = pipe(createSpec({ x: 'month', y: 'revenue' }), geom.bar(), scale.x(), scale.y());
const { scene } = createCompiler().compile({ spec, data });

In Node, prefer ES module imports. CommonJS requires Node 20.19+ or 22.12+.
