### 基本demo

 - [BMI计算](./?pywebio_api=bmi): 根据身高体重计算BMI指数 [源码](https://github.com/wang0618/PyWebIO/blob/master/demos/bmi.py)
 - [聊天室](./?pywebio_api=chat_room): 和当前所有在线的人聊天 [源码](https://github.com/wang0618/PyWebIO/blob/master/demos/chat_room.py)
 - [输入演示](./?pywebio_api=input_usage):  演示PyWebIO输入模块的用法 [源码](https://github.com/wang0618/PyWebIO/blob/master/demos/input_usage.py)
 - [输出演示](./?pywebio_api=output_usage): 演示PyWebIO输出模块的用法 [源码](https://github.com/wang0618/PyWebIO/blob/master/demos/output_usage.py)

### 数据可视化demo
PyWebIO还支持使用第三方库进行数据可视化

 - 使用`pyecharts`创建基于Echarts的图表 [**demos**]({charts_demo_host}/?pywebio_api=pyecharts)
 - 使用`cutecharts.py`创建卡通风格图表 [**demos**]({charts_demo_host}/?pywebio_api=cutecharts)
 - 使用`plotly`进行数据可视化 [**demos**]({charts_demo_host}/?pywebio_api=plotly)
