Apache ECharts, an open-source JavaScript visualization library, is available by default as echarts in Markdown. You can also import it explicitly like so:

import * as echarts from "npm:echarts";

To use ECharts, declare a container element with the desired dimensions, display it, and then call echarts.init.

const myChart = echarts.init(display(html`<div style="width: 600px; height:400px;"></div>`));
