Folium is a powerful Python library that helps you create several types of Leaflet maps. The library has a number of built-in tilesets from OpenStreetMap, Mapbox, and Stamen, and supports custom tilesets with Mapbox or Cloudmade API keys. Folium builds on the data wrangling strengths of the Python ecosystem and the mapping strengths of the Leaflet.js library. It allows you to manipulate your data in Python, then visualize it in on a Leaflet map via Folium.

Installation and Setup

Folium can be installed using pip with the command pip install folium or with conda using conda install -c conda-forge folium. Once installed, you can start by creating a basic map with just a few lines of code:

This code will create a map centered around the given coordinates and save it as an HTML file, which can be viewed in any web browser.
