Prompt engineering for interactive Python Streamlit maps

Interactive choropleth maps are powerful tools for visualizing and understanding complex datasets related to geographical areas.

Streamlit turns Python scripts into shareable web apps in minutes, no front-end experience required.

For data scientists and developers looking to provide interactivity for their users, Streamlit is the Python framework that can easily provide it.

And better yet, if we have a data set that we want to use, we can prompt GPT-4 to generate the Python code for us to create a pandas data frame — and to plug it into our Streamlit code!

Let’s step through how to do this with two awesome choropleth map examples:

For our first example, let’s create a choropleth map that uses a slider to navigate through yearly UN Global Peace Index (GPI) data.

This dataset can be downloaded from the website visionofhumanity.org. The GPI contains a numerical value indicating the relative peacefulness of 163 countries over a 15 year period (2008–2022).

This allows users to see how peace levels in different countries have evolved over time. Once we have downloaded the file, we… Read the full blog for free on Medium.
