数据可视化大屏的出现，掀起一番又一番的浪潮，众多企业主纷纷想要打造属于自己的“酷炫吊炸天”的霸道总裁大屏驾驶舱。
之前有小伙伴们建议我出一些视频课程来学习Echarts，这样可以更快上手，所以我就追星赶月的录制了《Echarts - 0基础入门课程》，希望对有需要的小伙伴有帮助。

一、 确定需求方案
1、确定产品上线部署的屏幕LED分辨率 本案例基于16:9 屏宽比，F11全屏显示。
2、部署方式基于免安装可执行程序：支持Windows、Linux、Mac等各种操作系统；将程序复制到服务器上即可，无需其它环境依赖；
观看方式：既可在服务器上直接观看程序界面，也可在远程用浏览器打开播放，例如Chrome浏览器、360浏览器等。
二、整体架构设计
三、编码实现 （关键代码） 1、前端html代码
- 前端基于Echarts开源库设计，使用WebStorm编辑器；
- 后端基于Java Web实现，使用 IDEA 编辑器；
- 数据传输格式：JSON；
- 数据源类型：目前采用JSON文件方式，自行添加Mybatis可支持PostgreSQL、MySQL、Oracle、Microsoft SQL Server、SQLite，自行添加Pandas可支持Excel表格等，还可以定制HTTP API接口方式。
- 数据更新方式：采用http get 轮询方式 。在实际应用中，也可以视情况选择j监测后端数据实时更新，实时推送到前端的方式；
