Pyecharts是一个用于生成 Echarts 图表的 Python 库。Echarts 是一个基于 JavaScript 的数据可视化库，提供了丰富的图表类型和交互功能。通过 Pyecharts，你可以使用 Python 代码生成各种类型的 Echarts 图表，例如折线图、柱状图、饼图、散点图等。

Pyecharts 提供了许多方便的 API 和方法，可以让你轻松地创建和定制自己的图表。以下是一些常用的 Pyecharts 方法：

Bar()：用于创建柱状图

Line()：用于创建折线图

Pie()：用于创建饼图

Scatter()：用于创建散点图

Option()：用于设置图表选项

render()：用于生成 HTML 文件并打开图表
