bytev-charts/lib/plugin/three.js/examples/js/geometries/BoxLineGeometry.js

基于echarts和JavaScript及ES6封装的一个可以直接调用的图表组件库，内置主题设计，简单快捷，且支持用户自定义配置； npm 安装方式: npm install bytev-charts 若启动提示还需额外install插件,则运行 npm install @babel/runtime-corejs2 即可;

import _Object$create from "@babel/runtime-corejs2/core-js/object/create";
