How to change the color, horizontal axis identification direction, display bar data number of st.bar_chart?
st.bar_chart is a convenience wrapper around st.altair_chart, for times when you want to make a quick chart just to observe your data.
When you have more complex situations, such as customizing the color and axes, the expectation is that you would use st.altair_chart to customize to your exact needs.
