    np.random.randn(40, 4),
    columns=["C1", "C2", "C3", "C4"])

# Bar Chart 
st.bar_chart(df)

Fix error: https://stackoverflow.com/a/73371225/3728901

[DouglasLivingstone]

The fix in the Stack Overflow post is to install protobuf==4.21 with pip, however in #5626 the comment from @willhuang1997 says that this would likely break:

Hi, yes there would be concerns for bumping protobuf! This would likely break streamlit as it's a major version change and would require a decent amount of refactoring.

As a workaround for this error, I've downgraded Streamlit to 1.15.2.

[crclark]

Upgrading protobuf is not a fix. Streamlit should fix the range on their protobuf dep.
