对于日常的python可视化过去用的都是Matplotlib可视化图表，但是这都是静态的图表，无法对图表进行交互。
今天介绍的pyecharts是经过网页渲染的可视化可交互的web页面图表，可以更好的时间选择或者维度选择进行交互，得到不同的动态图表。
汇总最常见的图表及代码：
1、柱状图
代码如下：

除此之外还有桑基图、旭日图、河流图、词云图、极坐标系、象型柱图、水球图等等常用图形。
以上的图形都可以进行组合，可以通过python代码自己根据需要设计自己的动态监控大屏。
以下是我自己爬取汽车数据，设计的汽车营销BI数据监控动态大屏。
以上类型的动态大屏还可以补充更多不同类型且炫丽的动态大屏，可以根据不同的行业和分析目的设计更多酷炫的动态大屏。
