近年来，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。今天为大家分享的是 【互联网热点分析案例】。
话不多说，开始分享干货，欢迎讨论！微信号： QQ6550523
首先看动态效果图 ：
再看实时分片数据图：
一、 确定需求方案
1、确定产品上线部署的屏幕LED分辨率
1280px*768px，F11全屏后占满整屏且无滚动条；其它分辨率屏幕均可自适应显示。
2、功能模块
1 水球图2 烟花图3 关系图4 中国地图，热力图，飞线图5 大数据词云图
3、部署方式
基于免安装可执行程序：支持Windows、Linux、Mac等各种主流操作系统；将可执行程序exe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，也可远程使用浏览器打开播放，支持Chrome浏览器、360浏览器等主流浏览器。
二、整体架构设计
前端基于Echarts开源库设计，使用WebStorm编辑器；后端基于Python Web实现，使用Pycharm编辑器；数据传输格式：JSON；数据源类型：目前已支持PostgreSQL、MySQL、Oracle、Microsoft SQL Server、SQLite、Excel表格等，还可以定制HTTP API接口方式或其它类型数据库。数据更新方式：摒弃了前端页面定时拉取的方式（这种方式带来严重的资源浪费），采用后端数据实时更新，实时推送到前端展示；
三、编码实现 （基于篇幅及可读性考虑，此处展示部分关键代码）
前端html代码

感谢：本项目引用了互联网大牛的前端代码，然后定制开发实现了后端服务器，最终实现了可视化大屏的完整方案。
