Interactive Map Design: Building Geographic Data Visualizations

Data is much more powerful when you can see where it lives. Whether you are analyzing urban trends, tracking environmental changes, or showcasing business locations, interactive maps turn static data into compelling geographic stories. In this written course, you will learn how to design, build, and publish interactive maps from scratch. You will start with the absolute fundamentals of geographic information systems (GIS) and spatial data formats, and then move on to styling, adding interactive layers, and deploying your maps online using modern web standards. What you'll learn: - Understand core geographic concepts, coordinate reference systems, and spatial data formats like GeoJSON. - Build dynamic web maps with markers, popups, and custom interactive elements. - Apply modern data-binding techniques to create choropleth maps that represent complex data visually. - Clean and prepare spatial datasets using beginner-friendly tools and libraries. - Design responsive map layouts that perform beautifully on both desktop and mobile devices. - Implement accessibility best practices to ensure your geographic visualizations are usable by everyone. The course starts with foundational definitions and key mapping terminology before guiding you step-by-step through data preparation, map styling, and interactive scripting. This text-based format allows you to read, analyze code snippets, and practice at your own pace. This course is designed for absolute beginners, with no prior GIS or programming experience required.
