G2 is a visualization grammar, a data-driven visual language with a high level of usability and scalability. It provides a set of grammars, takes users beyond a limited set of charts to an almost unlimited world of graphical forms. With G2, you can describe the visual appearance and interactive behavior of a visualization just by one statement, and generate web-based views using Canvas or SVG.

📦 Installation
$ npm install @antv/g2
🔨 Getting Started
Before drawing we need to prepare a DOM container for G2:
<div id="c1"></div>import { Chart } from '@antv/g2';
const data = [
{ genre: 'Sports', sold: 275 },
{ genre: 'Strategy', sold: 115 },
{ genre: 'Action', sold: 120 },
{ genre: 'Shooter', sold: 350 },
{ genre: 'Other', sold: 150 },
];
// Step 1: Create a Chart instance.
const chart = new Chart({
container: 'c1', // Specify chart container ID
width: 600, // Specify chart width
height: 300, // Specify chart height
});
// Step 2: Load the data.
chart.data(data);
// Step 3: Declare the grammar of graphics, draw column chart.
chart.interval().position('genre*sold');
// Step 4: Render chart.
chart.render();
