前言
🚀 基于 Echarts 实现可视化数据大屏响应式展示效果的源码,，基于html+css+javascript+echarts制作， 可以在此基础上重新开发。
本项目中使用的是echarts图表库，ECharts 提供了常规的折线图、柱状图、散点图、饼图、K线图，用于统计的盒形图，用于地理数据可视化的地图、热力图、线图，用于关系数据可视化的关系图、treemap、旭日图，多维数据可视化的平行坐标，还有用于 BI 的漏斗图，仪表盘，并且支持图与图之间的混搭。

一、Echart是什么
ECharts是一个使用 JavaScript 实现的开源可视化库，可以流畅的运行在 PC 和移动设备上，兼容当前绝大部分浏览器(IE8/9/10/11，Chrome，Firefox，Safari等)，底层依赖矢量图形库 ZRender，提供直观，交互丰富，可高度个性化定制的数据可视化图表。
