## What it is
G2 is a JavaScript/TypeScript visualization grammar library implementing the Grammar of Graphics, supporting canvas, SVG, and WebGL rendering. It provides a declarative API for building interactive charts for dashboards, data exploration, and storytelling.

## Use cases
- build interactive dashboards with charts
- create data visualizations in javascript
- declarative charting library for web apps
- explore data visually in the browser
- add animated and interactive charts to a web app
- implement grammar of graphics charts

## When to choose
- you want a flexible grammar-based charting approach rather than fixed chart types
- you need interactive, animated charts rendered via canvas, SVG, or WebGL
- you want a declarative API with high extensibility for custom marks, scales, and transforms

## When to avoid
- you need a simple high-level chart library with opinionated defaults and minimal configuration
- you are building non-web environments like native mobile or server-side image generation without a DOM/canvas
- your team prefers imperative chart APIs like ECharts-style option trees

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, animation
- domain: data-visualization, frontend, web-development, analytics
- platform: browser
- tags: grammar-of-graphics, charting, canvas, svg, webgl, declarative-api, antv, nodejs, javascript, typescript
