Computer Graphics in Python and Pycairo Course Syllabus

Overview: This course offers a hands-on introduction to computer graphics in Python using Pycairo, guiding you from foundational concepts to building interactive visualizations. Over 8 modules, each requiring approximately 5–7 hours, you'll gain practical experience in drawing vector graphics, applying transformations, working with color models, and exporting high-quality outputs. The course emphasizes code-first learning, real-world projects, and performance-aware rendering—culminating in a capstone project that integrates dynamic data and user interactivity. Lifetime access ensures you can learn at your own pace.
