index_md = r"""### Basic demo

 - [BMI calculation](./bmi): Calculating Body Mass Index based on height and weight [source](https://github.com/wang0618/PyWebIO/blob/dev/demos/bmi.py)
 - [Online chat room](./chat_room): Chat with everyone currently online [source](https://github.com/wang0618/PyWebIO/blob/dev/demos/chat_room.py)
 - [Input demo](./input_usage): Demonstrate various input usage supported by PyWebIO [source](https://github.com/wang0618/PyWebIO/blob/dev/demos/input_usage.py)
 - [Output demo](./output_usage): Demonstrate various output usage supported by PyWebIO [source](https://github.com/wang0618/PyWebIO/blob/dev/demos/output_usage.py)

### Data visualization demo
PyWebIO supports for data visualization with the third-party libraries.

 - Use `bokeh` for data visualization [**demos**]({charts_demo_host}/?app=bokeh)
 - Use `plotly` for data visualization [**demos**]({charts_demo_host}/?app=plotly)
 - Use `pyecharts` for data visualization [**demos**]({charts_demo_host}/?app=pyecharts)
 - Use `cutecharts.py` to create hand drawing style charts [**demos**]({charts_demo_host}/?app=cutecharts)
