接触Python有一段时间了，经常用来做一些好玩的事，前几天跟领导聊天说到，要是能够实现全国各地访问流量的显示，那就最好了，刚好要申请一些大屏幕来，所以就想到了做这个。确实稍微大点的公司都有这类东西，确实很酷炫了，自己也搞一个这样的。下面说一下实现过程：
1、首先是数据：采集的话我选择的是读取nginx日志。可以提供的思路是，我们选择同一收集的方式，收集到大数据分析机器(同意收集的工具还是很多的，比如rsyslog)，然后通过正则或者一类东西筛选出我们需要的IP（当然日志肯定是按天切割的）:
2、收集到的数据，通过调用公网的IP查询接口进行筛选，筛选，找出对应的城市、入库
3、最后就是前端展示了，这里我选用的是百度的echarts，百度已经提供了比较完善的API和说明文档，自己去阅读就好。
给一下前端的代码：
