Build Interactive Maps

Overview

This course starts with turning data into clear geographic stories that help people see where patterns are happening. In this short, hands-on course, you’ll learn how to move beyond static charts by building an interactive COVID-case choropleth map using Folium. You’ll explore how geographic boundaries and data values work together to reveal regional trends, and how design choices like color scales influence interpretation. As you progress, you’ll enhance your map with layer controls and informative popups that allow viewers to explore the data, toggle views, and access details directly on the map. Finally, you’ll complete the workflow by exporting your map as an HTML file and publishing it with GitHub Pages, creating a shareable link that works in any browser. Through guided videos, focused readings, and practical activities, you’ll practice moving from raw data to an interactive, web-based map that supports clear communication and informed discussion.

Syllabus

Visualizing COVID Data with Choropleth Maps

You are introduced to Folium and explore how choropleth maps communicate geographic patterns in data. Using COVID case data, learners build their first interactive choropleth map and understand how data values are translated into visual gradients.

Enhancing Interactivity with Layers and Popups

You will learn to enhance your maps by adding interactive features that allow users to explore data dynamically. This module focuses on usability, clarity, and stakeholder-friendly design.

Publishing and Sharing Maps Online

This module completes the workflow by moving maps from a local environment to the web. You will publish your interactive maps online so they can be shared with non-technical audiences.
