NameError: name 'folium_static' is not defined

This error message usually occurs in Python when the `folium_static` function is not defined or imported properly. This function is part of the `streamlit_folium` package, which provides a way to display interactive maps created with the `folium` library in a Streamlit app.

To fix this error, make sure that you have installed the `streamlit_folium` package and imported the `folium_static` function in your Python code. You can do this by adding the following lines at the beginning of your script:

import streamlit as st
from streamlit_folium import folium_static

Then, you can use the `folium_static` function to display your Folium map in your Streamlit app.
