Manim is an extremely versatile package. The following is an example Scene you can construct:

from manim import *


class SquareToCircle(Scene):
    def construct(self):
        circle = Circle()
        square = Square()
        square.flip(RIGHT)
        square.rotate(-3 * TAU / 8)
        circle.set_fill(PINK, opacity=0.5)

        self.play(Create(square))
        self.play(Transform(square, circle))
        self.play(FadeOut(square))

In order to view the output of this scene, save the code in a file called example.py. Then, run the following in a terminal window:

manim -p -ql example.py SquareToCircle

You should see your native video player program pop up and play a simple scene in which a square is transformed into a circle. You may find some more simple examples within this GitHub repository. You can also visit the official gallery for more advanced examples.

Manim also ships with a %%manim IPython magic which allows to use it conveniently in JupyterLab (as well as classic Jupyter) notebooks. See the corresponding documentation for some guidance and try it out online.
