SVG gives enormous scope to incorporate interactivity and animation. I have shown you interactions and animations using simple, often individual, graphical elements and shapes. In production settings, you might use more complex, perhaps grouped, graphics shapes and animate those on complex paths. The techniques you have been shown are time-based and event-based visual components that you can, and should, experiment with. Combining those visual components is what allows you to release your creative instincts through SVG.
