### 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`bokeh`进行数据可视化 [**demos**]({charts_demo_host}/?pywebio_api=bokeh)
 - 使用`plotly`进行数据可视化 [**demos**]({charts_demo_host}/?pywebio_api=plotly)
 - 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)
