This tutorial guides the reader through creating a boba tea shop finder with Python, Google Maps, and GeoJSON. The author starts by setting up the environment and dependencies, including installing necessary packages and generating an API key for the Google Maps API. They then create a class called `BubbleTea` to handle processing and methods for their bot. This includes using the Google Maps API to initialize authentication and pandas to read in the CSV file containing boba tea places and addresses. The author then converts the addresses into coordinates, creates shapely Point geospatial objects, and visualizes the data using GeoJSONio. Finally, they use the `visualize` method to deploy their visualization with GeoJSONio's display function.
