Animation and motion graphics can illustrate complex ideas visually. Think of motion graphics like a visual aid. Some ideas (especially big, abstract ones) are hard to explain with words or still images. A few seconds of motion graphics can clear everything up perfectly. This can be done on a website with pure code and CSS or in the form of a video file.
Animation is used for stories. Anyone who’s seen a Pixar film knows that animation can be a powerful storytelling medium. Motion graphics can bring statistical data to life, but animation can bring characters to life with emotional narratives, creativity, and artistic expression.
