大家好，我是java1234_小锋老师，看到一个不错的于Python豆瓣电影数据分析及可视化系统(Flask+echart+pandas)【论文+源码+SQL脚本】，分享下哈。

项目介绍

随着如今电影越来越多，各种各样的烂片和捞钱的商业片也层出不穷，而有意义的电影慢慢的变得很少。本项目是基于对豆瓣网的子网站豆瓣电影的网络爬虫技术到数据可视化分析的实现，从Pycharm的环境搭建到数据爬取，再数据处理，最后数据的可视化。该项目通过爬虫爬取目标网站，获取数据，在数据可视化的过程中，使用ECharts对做出的图表进行可视化处理，可以提高用户在需要时查找所需要信息的识别率，通过图表让人一目了然，比如一些多角度动态视图，解决了用户首次了解解决率如何，从而显著提高用户对电影的满意程度。
