Production Design
Digital Animation
If you were born during or after the 1990's, then you might just call this animation. But believe it or not, animators used to draw everything by hand. With pen and paper and stuff. That must've taken a hot second.
The Incredibles, on the other hand, is a prime example of the digital animation style that made Pixar famous. Although the graphics are rather basic by today's standards, the use of simple shapes and bold designs help the film stand the test of time despite ample technological progress since its release. That being said, if you compare screenshots of The Incredibles and The Incredibles 2, the difference is like night and day.
