Let's use the st.checkbox function to add a
checkbox to your app. We'll use this checkbox to show/hide the raw data
table at the top of your app.
Locate these lines:
python
   st.subheader('Raw data')
   st.write(data)
Replace these lines with the following code:
python
   if st.checkbox('Show raw data'):
       st.subheader('Raw data')
       st.write(data)
We're sure you've got your own ideas. When you're done with this tutorial, check out all the widgets that Streamlit exposes in our API Reference.
Let's put it all together
That's it, you've made it to the end. Here's the complete script for our interactive app.
If you've skipped ahead, after you've created your script, the command to run
Streamlit is streamlit run [app name].
```python
import streamlit as st
import pandas as pd
import numpy as np
