Django & Folium - Displaying Maps of Database Data in Django Apps

📚 Geospatial Python Playlist:    • Geospatial Python  
☕ Buy a coffee: ko-fi.com/bugbytes

In this video, we use Folium to create maps and use Django to fetch data from the database and plot that geographical data as markers on the map.

We show how to convert the Folium Map object to an HTML representation with the _repr_html_() function, and display the map in our Django template.

We also see how to add popups and clusters to the map, as well as how to filter which markers are shown using Django ORM operations.
