Excellent tutorial! I love the way you broke down the Django template structure.

I found NOAA Lightning dataset in Google BigQuery public datasets. You need a Google Cloud Platform login to access it, but the dataset is public. https://console.cloud.google.com/marketplace/product/noaa-public/lightning

Thanks for the tutorial. Showing your process of transforming the dates to dt to months is very helpful. Could you share a link to the data, so we can try this tutorial?

Wonderful article, Alex! I appreciate your detailed explanation, github source and final product. I've been creating maps directly in Javascript and Leaflet after transforming the data in Python. I'll try Folium and do it all in Python.
