Welcome to Module 4: Prototyping & Iteration! In the previous modules, you’ve explored the foundations of data visualization, mastered data preparation, and learned how to select appropriate visual encodings. Now, it's time to bring your designs to life through prototyping and refinement. This module will equip you with the essential skills to transform your abstract visualization ideas into tangible representations. You'll learn how to create quick and efficient low-fidelity prototypes, gather valuable feedback through usability testing, and refine your designs through an iterative process. By the end of this module, you will be able to: Create effective low-fidelity prototypes for data visualizations. Conduct basic usability testing to gather user feedback. Apply the iterative design process to enhance your visualization designs. Let's dive in and start building your visualization prototypes! The Purpose of Prototyping A prototype is a preliminary model, mockup, or ...
