Build Interactive Maps

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
